Use of new types of carbonaceous materials such as reduced graphene oxide instead of traditional active carbon provides certain benefits. Although the rutile polymorph of TiO2 seems to have the most beneficial properties in these hybrid materials, the anatase type is more frequent in TiO2-rGO composites, especially in graphite oxide (GO) derived ones, as GO has several properties which may interfere with rutile formation. To explore and evaluate these peculiarities and their influence on the composite formation, we compared TiO2-C systems formulated with GO and Black Pearls (BP) carbon. Various physicochemical methods, such as attenuated total reflection infrared (ATR-IR)-, solid state NMR-, Raman- and X-ray photoelectron spectroscopy, X-ray powder diffraction (XRD), electron microscopy, etc. were used to characterize the samples from the different stages of our multistep sol–gel synthesis. Our experiments demonstrated that utilization of GO is indeed feasible for composite preparation, although its sodium contamination has to be removed during the synthesis. On the other hand, high temperature treatment and/or solvothermal treatment during composite synthesis resulted in decomposition of the functional groups of the GO and the functional properties of the final product were similar in case of both composites. However, Pt/TiO2-GO derived sample showed higher oxygen reduction reaction activity than Pt/TiO2-BP derived one. Based on the decrease of electrochemical surface area, the stability order was the following: Pt/C (commercial) < Pt/TiO2-BP derived C < Pt/TiO2-GO derived C. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.}, year = {2024}, eissn = {1572-9028}, orcid-numbers = {Szabó, Tamás/0000-0001-8182-640X; Nyergesné Illés, Erzsébet/0000-0002-2901-9616; Florea, Mihaela/0000-0002-6612-6090} } @article{MTMT:34037885, title = {Thermal characterization of leathers tanned by metal salts and vegetable tannins}, url = {https://m2.mtmt.hu/api/publication/34037885}, author = {Czirok, István Sándor and Pekkerné Jakab, Emma and Czégény, Zsuzsanna and Badea, E. and Babinszki, Bence and Tömösközi, Sándor and May, Zoltán and Sebestyén, Zoltán}, doi = {10.1016/j.jaap.2023.106035}, journal-iso = {J ANAL APPL PYROL}, journal = {JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS}, volume = {173}, unique-id = {34037885}, issn = {0165-2370}, year = {2023}, eissn = {1873-250X} } @article{MTMT:33133627, title = {In situ formation of fatty acid methyl esters via thermally assisted methylation by lignin during torrefaction of oil palm biomass}, url = {https://m2.mtmt.hu/api/publication/33133627}, author = {Babinszki, Bence and Pekkerné Jakab, Emma and Terjék, Viktor and Sebestyén, Zoltán and Czirok, István Sándor and Bozi, János and Attanatho, Lalita and Thanmongkhon, Yoothana and Czégény, Zsuzsanna}, doi = {10.1016/j.jaap.2022.105720}, journal-iso = {J ANAL APPL PYROL}, journal = {JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS}, volume = {168}, unique-id = {33133627}, issn = {0165-2370}, year = {2022}, eissn = {1873-250X} } @article{MTMT:32636134, title = {Characterization of historical leather bookbindings by various thermal methods (TG/MS, Py-GC/MS, and micro-DSC) and FTIR-ATR spectroscopy}, url = {https://m2.mtmt.hu/api/publication/32636134}, author = {Sebestyén, Zoltán and Badea, Elena and Carsote, Cristina and Czégény, Zsuzsanna and Szabó, Tímea and Babinszki, Bence and Bozi, János and Pekkerné Jakab, Emma}, doi = {10.1016/j.jaap.2021.105428}, journal-iso = {J ANAL APPL PYROL}, journal = {JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS}, volume = {162}, unique-id = {32636134}, issn = {0165-2370}, year = {2022}, eissn = {1873-250X} } @article{MTMT:32114294, title = {Thermo-catalytic studies on a mixture of plastic waste and biomass}, url = {https://m2.mtmt.hu/api/publication/32114294}, author = {Sebestyén, Zoltán and Blazsó, Marianne and Pekkerné Jakab, Emma and Miskolczi, Norbert and Bozi, János and Czégény, Zsuzsanna}, doi = {10.1007/s10973-021-10962-5}, journal-iso = {J THERM ANAL CALORIM}, journal = {JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY}, volume = {147}, unique-id = {32114294}, issn = {1388-6150}, year = {2022}, eissn = {1572-8943}, pages = {6259-6270}, orcid-numbers = {Blazsó, Marianne/0000-0002-5413-7956; Miskolczi, Norbert/0000-0003-4862-0148} } @article{MTMT:32112656, title = {Effect of slow pyrolysis conditions on biocarbon yield and properties: Characterization of the volatiles}, url = {https://m2.mtmt.hu/api/publication/32112656}, author = {Babinszki, Bence and Sebestyén, Zoltán and Pekkerné Jakab, Emma and Kőhalmi, L and Bozi, János and Várhegyi, Gábor and Wang, L and Skreiberg, Ø and Czégény, Zsuzsanna}, doi = {10.1016/j.biortech.2021.125567}, journal-iso = {BIORESOUR TECHNOL}, journal = {BIORESOURCE TECHNOLOGY}, volume = {338}, unique-id = {32112656}, issn = {0960-8524}, abstract = {Slow pyrolysis of spruce and birch was performed at various heating programs and conditions in a horizontal quartz tube reactor heated by an electric furnace.

The thermal properties, volatile matter (VM) content and the evolution profiles of volatiles from the biocarbons were characterized by thermogravimetry/mass spectrometry. The composition of volatiles was analyzed in detail by pyrolysis-gas chromatography/mass spectrometry. Increased char yield was observed when staged pyrolysis program, low purging flow rate or covered sample holder were applied. Spruce produced more charcoal than birch due to the higher lignin content of softwood. The amount and the evolution profiles of the main gaseous products were similar from spruce and birch biocarbons prepared under the same conditions. The relative amount of aromatic and polyaromatic compounds in VM drastically decreased with increasing carbonization temperature.}, keywords = {BIOMASS; Carbonization; TG/MS; Py-GC/MS; biocarbon}, year = {2021}, eissn = {1873-2976} } @article{MTMT:31987939, title = {CBD, a precursor of THC in e-cigarettes}, url = {https://m2.mtmt.hu/api/publication/31987939}, author = {Czégény, Zsuzsanna and Brezina-Nagy, Gréta and Babinszki, Bence and Bajtel, Ákos and Sebestyén, Zoltán and Kiss, Tivadar and Csupor-Löffler, Boglárka and Tóth, Barbara and Csupor, Dezső}, doi = {10.1038/s41598-021-88389-z}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {11}, unique-id = {31987939}, issn = {2045-2322}, year = {2021}, eissn = {2045-2322}, orcid-numbers = {Bajtel, Ákos/0000-0003-2128-6522; Kiss, Tivadar/0000-0003-3538-377X; Tóth, Barbara/0000-0002-6086-8819; Csupor, Dezső/0000-0002-4088-3333} } @article{MTMT:31901992, title = {Thermal decomposition of biomass wastes derived from palm oil production}, url = {https://m2.mtmt.hu/api/publication/31901992}, author = {Babinszki, Bence and Pekkerné Jakab, Emma and Terjék, Viktor and Sebestyén, Zoltán and Várhegyi, Gábor and May, Zoltán and Mahakhant, Aparat and Attanatho, Lalita and Suemanotham, Amornrat and Thanmongkhon, Yoothana and Czégény, Zsuzsanna}, doi = {10.1016/j.jaap.2021.105069}, journal-iso = {J ANAL APPL PYROL}, journal = {JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS}, volume = {155}, unique-id = {31901992}, issn = {0165-2370}, year = {2021}, eissn = {1873-250X}, orcid-numbers = {Várhegyi, Gábor/0000-0002-2933-1845; Czégény, Zsuzsanna/0000-0001-9636-9547} } @article{MTMT:31522473, title = {CO tolerant Pt electrocatalysts for PEM fuel cells with enhanced stability against electrocorrosion}, url = {https://m2.mtmt.hu/api/publication/31522473}, author = {Borbáth, Irina and Zelenka, Kristóf and Vass, Ádám and Pászti, Zoltán and Szijjártó, Gábor and Sebestyén, Zoltán and Sáfrán, György and Tompos, András}, doi = {10.1016/j.ijhydene.2020.08.002}, journal-iso = {INT J HYDROGEN ENERG}, journal = {INTERNATIONAL JOURNAL OF HYDROGEN ENERGY}, volume = {46}, unique-id = {31522473}, issn = {0360-3199}, year = {2021}, eissn = {1879-3487}, pages = {13534-13547}, orcid-numbers = {Vass, Ádám/0000-0002-8012-9511; Sáfrán, György/0000-0003-3708-3551} } @article{MTMT:31799730, title = {Thermo-Oxidative Decomposition of Lovage (Levisticum officinale) and Davana (Artemisia pallens) Essential Oils under Simulated Tobacco Heating Product Conditions}, url = {https://m2.mtmt.hu/api/publication/31799730}, author = {Pekkerné Jakab, Emma and Sebestyén, Zoltán and Babinszki, Bence and Barta-Rajnai, Eszter and Czégény, Zsuzsanna and Nicol, James and Clayton, Peter and Liu, Chuan}, doi = {10.2478/cttr-2020-0004}, journal-iso = {BEITR TABAKFORSCH INT}, journal = {BEITRAGE ZUR TABAKFORSCHUNG INTERNATIONAL}, volume = {29}, unique-id = {31799730}, issn = {0173-783X}, year = {2020}, eissn = {1612-9237}, pages = {27-43} }
