As a result, the development of renewable and clean energy depends largely on hydrogen as a key component. Even, nanomaterial procured from waste for Hydrogen synthesis can be processed through several biochemical/thermochemical procedures. Variables comprising feedstock characteristics, operation needs and technology availability were examined to support technology choice and system features. Such amendments proceed with costly synthesis and operation strategies, low operating efficiencies, insufficient management along with logistics, as well as lack of operation policies. Perhaps, nanotechnology is now crucial in the creation of nanomaterials for the production of hydrogen as a pertinent origin through renewable energy causatives. Nanomaterials have received a great deal of interest in recent years owing to their unusual mechanical, electrical, electronic, optical, and magnetic properties on their surfaces. These features had a predominant impact on the evolution of production and storage techniques, as well as the difficulties experienced in bringing the product to market. This article provides an overview of the nanomaterials that contributed to hydrogen synthesis, storage, and usage.

Recently, a lot of researchers have focused on the improvement of the photocatalytic properties of catalysts through modifying and co-modifying them with different metals and nonmetals. These co-catalytic ions improve the photocatalytic activity of ZnO and TiO2 by reducing its energy band gap. This might be useful in wastewater treatment for the photocatalytic degradation of organic contaminants. In this study, we prepared semiconductor films that were surface-modified with Ag co-catalyst layers via the photo-fixation of Ag (I) ions with varied concentrations (10−2–10−4 M) in the water phase under UV illumination for the first time. The photocatalytic behavior was evaluated by the degradation of malachite green and methylene blue under UV and visible light irradiation. The ZnO/Ag and TiO2/Ag samples showed a faster degradation of malachite green compared to methylene blue due to the formation of stable intermediates by the reaction of OH radicals with the triarylmethane dye (C=C bond) during the photocatalysis. The co-catalytic-silver-modified films had a higher photocatalytic efficiency in comparison with the pure nanostructures. The dye photodegradation rate constants increased in the following order: pure films < films modified with Ag, 10−4 M < films modified with Ag10−3 M < films modified with Ag10−2 M. The Ag modification and the heterojunction of the composites contributed to trapping and transfer of the electrons. Therefore, the photogenerated charges had a longer lifetime, resulting in a strengthened photocatalytic ability of the ZnO/Ag and TiO2/Ag films. © 2023 by the authors.}, keywords = {TIO2; ZnO; Photocatalysis; sol-gel; co-catalytic silver modification}, year = {2023}, eissn = {2073-4344} } @article{MTMT:33836739, title = {Development of visible light-driven SrTiO3 photocatalysts for the degradation of organic pollutants for waste-water treatment: Contrasting behavior of MB & MO dyes}, url = {https://m2.mtmt.hu/api/publication/33836739}, author = {Mehra, Sonali and Saroha, Jyoti and Rani, Ekta and Sharma, Vikash and Goswami, Lalit and Gupta, Govind and Srivastava, A.

There are various complex energy -consuming techniques used for the refinement of wastewater. However, the photocatalysis process is the cleanest technique used for degrading organic pollutants in wastewater into the water; carbon dioxide, other small molecules, and inorganic pollutants were reduced or oxidized into harmless substances.SrTiO3 nanoparticles (NPs) synthesized by the chemical method are the topic of attention among researchers because of their physical, chemical & photocatalytic properties under sunlight for water purification applica-tions. This paper dealt with the study of The photocatalytic properties of SrTiO3 and its composites under sunlight irradiation. Here, we evaluated the photodegradation of methyl orange (MO) and methylene blue (MB) pollutants using SrTiO3 as a photocatalyst for de-ionized (DI) water and hard water, respectively. Later on, the ex-situ decoration of Ag and Au nanoparticles (NPs) on SrTiO3 NPs results in enhancing the photocatalytic ac-tivity of SrTiO3. This article shows the abnormal behaviour of MO degradation compared to MB dye because there was no degradation of methyl orange for both bare SrTiO3 and Ag, Au@SrTiO3 nanocomposites. However, for bare-SrTiO3, the photocatalytic degradation of MB dye for de-ionized and hard water was accomplished in 210 min and 300 min, respectively. Here, SrTiO3 with MB dye shows enhanced photocatalytic activity for de -ionized water than hard water, and thus we determined the degradation of SrTiO3 nanocomposites with DI water only. While in the case of SrTiO3 nanocomposites, degradation occurred in 210min for Ag and 180 min for Au in DI water which signifies that Au a better co-catalyst for photodegradation. Although, degradation of MO in both DI water and hard water does not show any photocatalytic activity even in 6 and 7 h, respectively, for bare SrTiO3 and its nanocomposites. Therefore, it gives an idea about the different behaviour of dyes in photocatalytic degradation of DI and hard water using bare SrTiO3 and noble metal doped SrTiO3 as photocatalysts for water remediation applications.At a glimpse, this work focus on the photocatalytic removal of various water pollutants using the efficient noble metal (Au & Ag) doped SrTiO3 as a photocatalyst and discusses the properties of those materials and also discuss the prospects for the utilization of those photocatalysts in complex form for the wastewater treatment.}, keywords = {Photocatalysis; organic pollutants; perovskite; Noble -metals; Water-remediation}, year = {2023}, eissn = {1873-1252} } @article{MTMT:33854573, title = {Advanced photocatalysis mediated by TiO2/Ag/TiO2 nanoparticles modified cotton fabric}, url = {https://m2.mtmt.hu/api/publication/33854573}, author = {Milosevic, Milica and Radoicic, Marija and Ohara, Satoshi and Abe, Hiroya and Spasojevic, Jelena and Mancic, Lidija and Saponjic, Zoran}, doi = {10.1007/s10570-023-05165-0}, journal-iso = {CELLULOSE}, journal = {CELLULOSE}, volume = {30}, unique-id = {33854573}, issn = {0969-0239}, abstract = {Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP-OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules.

Ag migration into purified water was detected but was below the limit of ICP-MS quantitation, giving a range of potential Ag migration between 0.059 and 0.082 ng cm(-2) packaging surface area. Ag migration into 9 wt% aqueous sucrose solution was 0.547 +/- 0.084 ng cm(-2) and migration into 9 wt% sucrose solution containing 0.01 wt% mu TiO2 was 0.724 +/- 0.032 ng cm(-2). Total Ag migration into a 0.01 wt% mu TiO2 aqueous dispersion without sucrose was between 0.122 and 0.162 ng cm(-2), with upper and lower limits defined by the detectability of Ag in the supernatant phase of the simulant. If the midpoint of this range is taken as a baseline, these results imply that, compared to purified water, Ag migration was increased by approximately 10.3 times when the water simulant contained mu TiO2 and sucrose at commercially-relevant concentrations. Notably, the Ag migrated into water containing both ingredients exceeded the total Ag migrated into either of the single-ingredient simulants, pointing to a potential cooperative relationship between sucrose and mu TiO2 that possibly derives from binding and redox interactions between these two ingredients. Sucrose and mu TiO2 also both reduced a portion of migrated Ag+ back into AgNPs, and mu TiO2 particles efficiently captured (>25% by mass) migrated Ag on their surfaces. Similar effects on migration were observed with nanocrystalline TiO2. These experiments are the first to show that TiO2 particles exert a strong influence on the quantity and form of Ag that could migrate from AgNP-enabled packaging, suggesting that food formulations and interactions between individual food components may be important to consider when evaluating the fate of nanoparticles in these consumer applications.}, year = {2023}, eissn = {2051-8161}, pages = {1689-1703}, orcid-numbers = {Bleher, Reiner/0000-0003-0962-797X} } @article{MTMT:32948696, title = {Multifunctional and smart Er2O3-ZnO nanocomposites for electronic ceramic varistors and visible light degradation of wastewater treatment}, url = {https://m2.mtmt.hu/api/publication/32948696}, author = {AlAbdulaal, Thekrayat and AlShadidi, Manal and Hussien, Mai and Ganesh, Vanga and Bouzidi, Abdel-Fatah and Rafique, Saqib and Algarni, Hamed and Zahran, Heba and Abdel-wahab, Mohamed and Yahia, Ibrahim}, doi = {10.1007/S11356-021-16754-6}, journal-iso = {ENVIRON SCI POLLUT R}, journal = {ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH}, volume = {29}, unique-id = {32948696}, issn = {0944-1344}, abstract = {In this proposed study, erbium (Er3+)-doped ZnO nanocomposites were prepared through the effective, basic, and green combustion method.

In the process, TiO2 thin film was deposited on the glass slide followed by being enfolded in copper (Cu) foil to initiate polymerization and synthesize Gry on the surface of TiO2 directly. It turns out that with co-catalyst Platinum (Pt) the efficiency of TiO2-Gry with introduction of only 1.9 wt% Gry is 12.6% higher than the efficiency of TiO2 under same test conditions. The improvement is attributed to band structure of the combined material and efficiency of charge transfer. In this system, Gry acts as an excellent medium for charge transfer, which benefits from its intrinsic property and effective contact with TiO2 by this synthesis. The work points out a new way to get well-combined platelike photocatalyst on transparent substrate.

The percentage degradation of p NBA using goethite (alpha-FeOOH) and hematite (alpha-Fe2O3) was 70.54% and 85.5% with the nano concentration 0.07 g respectively using visible light. Hence, hydrothermal mode of nano synthesis at elevated temperature can be a better option for photocatalytic degradation of organic pollute using visible light. (C) 2019 Elsevier Ltd.

XRD confirm the formation of hexagonal wurtzite phase of ZnO. Further, doping of Er and Yb in to ZnO lattice was evidenced by shift of XRD planes towards lower 2 theta values. The addition of Er and Yb introduces significant changes in light absorption characteristics with important absorbance in visible region due to Er and Yb role as acceptor to increase charge separation.

In particular, EYZO with maximum Er and Yb content allowed obtaining the almost complete MO degradation only in 90 min under visible light irradiation.

In this work, degradation of 4-hydroxybenzenesulfonic acid (4-HBS, a key intermediate of the decomposition of benzenesulfonic acid) was thoroughly studied by application of the above mentioned procedures individually and also in various combinations. Detailed comparisons of these methods were realized by measurements of degradation and mineralization of 4-HBS as well as determination of characteristic hydroxy intermediates and sulfate ions. The degradation efficiency of combination of Ag-TiO2 based photocatalysis and ozonation was just about the sum of the efficiencies of the individual procedures, while mineralization efficacy of this combination, however, proved to be highly synergic, considerably exceeding this feature of the air- Ag-TiO2 system, due to the increased rate of ozone decay producing ring-opening radicals. Accordingly, total mineralization of 4-HBS was realized under these conditions. Ozonation, however, caused an oxidative dissolution of the deposited silver from the surface of the catalyst. Even so, simultaneous application of Ag-TiO2 based heterogeneous photocatalysis and ozonation led to total mineralization faster than their consecutive combination did.}, keywords = {Ozonation; Silver deposition; 4-hydroxybenzenesulfonic acid; TiO2 based heterogeneous photocatalysis}, year = {2018}, eissn = {1873-2666}, pages = {152-161}, orcid-numbers = {Fónagy, Orsolya/0000-0003-3128-4408; Szabóné Bárdos, Erzsébet/0000-0002-2290-0240; Horváth, Ottó/0000-0002-5325-8430; Kiss, Gyula/0000-0002-1678-6672} } @inbook{MTMT:27362763, title = {Nanotechnology.

Fine and low-scale control of the size of resulting Pt nanoparticles was obtained through variation of the trisodium citrate concentration during the syntheses. The reducing reagent was NaBH4.

The results. clearly indicated that TiO2-based heterogeneous photocatalysis combined with zonation can efficiently decrease the COD value of the effluent from the cleaning plant currently applied, thus a final biological treatment ensures the required new (higher) level of purity. However, for wastewaters of large volume, which are generally mixtures of various process waters of different origins, the application of this heterogeneous photocatalysis at the end of the purification chain is not reasonable because of the high costs of investment. Insertion of the combined method into the middle of the cleaning technology, as a pre-treating stage of a heavily polluted constituent (an emulsion in this case) of the whole mixture before the biological treatment, is more cost effective. In the most economical procedure the combined method is applied for the emulsion diluted with weakly polluted wash waters.

Liquid chromatography-mass spectrometry analysis was utilized for the detection of intermediates formed during the irradiation in the UVA range (λmax = 350 nm). The results obtained by these analytical techniques indicate that the initial step of degradation is hydroxylation of the starting surfactant, resulting in the production of hydroxy- and dihydroxybenzenesulfonates. These reactions were accompanied by desulfonation, which increases [H+] in both argon-saturated and aerated systems. In accordance with our previous theoretical calculations, the formation of ortho- and meta-hydroxylated derivatives is favored in the first step. The main product of the further oxygenation of these derivatives was 2,5-dihydroxy-benzesulfonate. No decay of the hydroxy species occurred during the 8-h irradiation in the absence of dissolved oxygen. In the aerated system much more efficient desulfonation and hydroxylation, moreover, a significant decrease of TOC took place at the initial stage. Further hydroxylation led to cleavage of the aromatic system, due to the formation of polyhydroxy derivatives, followed by ring fission, resulting in the production of aldehydes and carboxylic acids. Total mineralization was achieved by the end of the 8-h photocatalysis. It has been proved that in this photocatalytic procedure the presence of dissolved oxygen is necessary for the cleavage of the aromatic ring because hydroxyl radicals photochemically formed in the deaerated system too alone are not able to break the C-C bonds. © 2010 Elsevier Ltd.}, keywords = {PH;
