	abstract = {Catalysts with magnetic properties can be easily recovered from the reaction medium without loss by using a magnetic field, which highly improves their applicability. To design such systems, we have successfully combined the magnetic properties of nickel ferrite nanoparticles with the positive properties of carbon-based catalyst supports. Amine-functionalized NiFe2O4 nanoparticles were deposited on the surfaces of nitrogen-doped bamboo-like carbon nanotubes (N-BCNT) and carbon nanolayers (CNL) by using a coprecipitation process. The magnetizable catalyst supports were decorated by Pd nanoparticles, and their catalytic activity was tested through the hydrogenation of nitrobenzene (NB). By using the prepared catalysts, high nitrobenzene conversion (100% for 120 min at 333 K) and a high aniline yield (99%) were achieved. The Pd/NiFe2O4-CNL catalyst was remarkable in terms of stability during the reuse tests due to the strong interaction formed between the catalytically active metal and its support (the activity was retained during four cycles of 120 min at 333 K). Furthermore, despite the long-lasting mechanical stress, no significant palladium loss (only 0.08 wt%) was detected.},

	abstract = {Thermo-catalytic bio-SNG (CH4) production is one of the useful tools for converting waste to gaseous fuels through CO2 conversion. To abundant properly, however, efficient, robust and cost-effective catalysts would be required. Bimetallic systems based on transition metals seem to be promising candidates for this task. The CoCu bimetallic system with in-situ generated interfaces was synthesized and used as a catalyst for CO2 methanation. The in-depth analysis of the structure-activity-selectivity relationships involving XRD, (NAP-)XPS, EXAFS and TEM-EDX revealed that the co-existence of Co0, CoO, and Cu0 in the proper distribution on the surface can ensure the selective production of methane. To fine-tune the surface composition of the bimetallic systems, a systematic alteration of the Cu:Co ratio in the precursor spinel structures must be performed. Cu0.4Co2.6O4 derivative, stabilizing subsurface Cu(I)–O specimen, showed the best performance with high activity (12,800 nmol g–1 s–1) and a remarkable selectivity of 65–85% for methane in a wide temperature range (250–425 °C). In studying the mechanistic aspects of methanation, it has been shown that the hydrogenation of active carbon at the surface or below the surface is the key step for the production of methane. So far, this cobalt-catalyzed sub-step has been proposed in catalytic Fischer-Tropsch syntheses.},

	abstract = {MoO3 is an intensively researched metal oxide, and it is considered a promising visible light driven photocatalyst and an excellent adsorbent of cationic dyes. In the present work orthorhombic α-MoO3 was obtained via calcination of ammonium heptamolybdate where structural modifications were induced by changing the applied calcination temperature (400–750 °C). Further subtle structural (crystallographic plane ratio) and morphological modifications were achieved via hydrothermal recrystallization. Differences between samples were clearly evidenced by various characterization techniques, especially in the case of the crystalline facet ratio and the morphology. The differently structured α-MoO3 samples were investigated as an inhibitor for Fenton reactions where the organic compounds decomposition relies on the generation of [rad]OH radicals. It was found that α-MoO3 strongly inhibits the rate of methyl orange (MO) decolorization. This might imply that MoO3 could be a [rad]OH radical scavenger since Fenton reactions’ effectivity relies on the presence of [rad]OH and [rad]O2 – radicals. We demonstrated that the inhibition efficiency of α-MoO3 correlates strongly with the acidification rate of the aqueous solution in the presence of α-MoO3. However, this pH decline was consistent with crystalline facet ratio within a sample series, while the recrystallized samples disprove this structural connection showing a more complex relationship between the structural characteristics of α-MoO3 and its inhibitive properties of Fenton reactions. The present work pointed out that MoO3 can inhibit reactions which are based on intensive OH radical generation processes such as photocatalysis. © 2023},

	abstract = {Strontium titanate (STO) photocatalysts were prepared via a slightly modified Pechini sol–gel method. A unique rapid calcination technique with a short exposure time was used to obtain crystalline products. The samples were characterized by X-ray diffractometry, scanning electron microscopy, diffuse reflectance spectroscopy, infrared spectroscopy, nitrogen adsorption–desorption measurements, and X-ray photoelectron spectroscopy. Their photocatalytic activity was evaluated by the photocatalytic oxidation of phenol, oxalic acid, and chlorophenol under UV light irradiation using commercial STO as a reference. These pollutants, together with glucose and propanol, were used to investigate the stability of the samples against various functional groups. All our samples exhibited higher photocatalytic activity than the commercial STO reference. With increasing calcination temperature, the crystallinity and primary crystallite sizes increased while the band gaps and specific surface areas decreased. The photocatalytic activity of the most efficient sample was explained by the presence of SrCO3 on its surface. The STO catalysts were highly stable as they largely retained their crystalline composition after exposure to chemicals with different functional groups. Finally, we compared the costs associated with the unique calcination technique with a more conventional one and found that our method is ~35% more cost-effective.},
