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} } @CONFERENCE{MTMT:34453955, title = {Magnetic flower-like nanostructures prepared by different methods}, url = {https://m2.mtmt.hu/api/publication/34453955}, author = {Varga, Viktória and Nyergesné Illés, Erzsébet}, booktitle = {16th International Conference on Magnetic Fluids (ICMF23), Book of Abstracts}, unique-id = {34453955}, year = {2023}, pages = {137}, orcid-numbers = {Varga, Viktória/0000-0001-9933-7604; Nyergesné Illés, Erzsébet/0000-0002-2901-9616} } @CONFERENCE{MTMT:34453953, title = {Interplay between magnetic properties and colloidal stabilization in bio-ferrofluids}, url = {https://m2.mtmt.hu/api/publication/34453953}, author = {Nyergesné Illés, Erzsébet and V., Kusigerski and Szabó, Tamás and Csákiné Tombácz, Etelka}, booktitle = {16th International Conference on Magnetic Fluids (ICMF23), Book of Abstracts}, unique-id = {34453953}, year = {2023}, pages = {140}, orcid-numbers = {Nyergesné Illés, Erzsébet/0000-0002-2901-9616; Szabó, Tamás/0000-0001-8182-640X; Csákiné Tombácz, Etelka/0000-0002-2068-0459} } @CONFERENCE{MTMT:34453950, title = {Biocompatible folate targeted cobalt ferrite nanoparticles for magnetic hyperthermia}, url = {https://m2.mtmt.hu/api/publication/34453950}, author = {Nyergesné Illés, Erzsébet and M., Cobianchi and C., Scialabba and M., Licciardi and V., Kusigerski and D., Peddis}, booktitle = {16th International Conference on Magnetic Fluids (ICMF23), Book of Abstracts}, unique-id = {34453950}, year = {2023}, pages = {53}, orcid-numbers = {Nyergesné Illés, Erzsébet/0000-0002-2901-9616} } @{MTMT:34453932, title = {Preparation and stability testing of flavoured whipped cream with lyophilized ingredients}, url = {https://m2.mtmt.hu/api/publication/34453932}, author = {Zsolt, Garzó and Nyergesné Illés, Erzsébet}, booktitle = {Proceedings of the 29th International Symposium on Analytical and Environmental Problems}, unique-id = {34453932}, year = {2023}, pages = {150}, orcid-numbers = {Nyergesné Illés, Erzsébet/0000-0002-2901-9616} } @{MTMT:34453930, title = {Effect of synthesis conditions on the properties of magnetic nanoflowers}, url = {https://m2.mtmt.hu/api/publication/34453930}, author = {Varga, Viktória and Nyergesné Illés, Erzsébet}, booktitle = {Proceedings of the 29th International Symposium on Analytical and Environmental Problems}, unique-id = {34453930}, year = {2023}, pages = {369}, orcid-numbers = {Varga, Viktória/0000-0001-9933-7604; Nyergesné Illés, Erzsébet/0000-0002-2901-9616} } @{MTMT:34453926, title = {Magnetic properties and hemocompatibility of various ferrite nanoparticles}, url = {https://m2.mtmt.hu/api/publication/34453926}, author = {Anna, Katalin Vas and Nyergesné Illés, Erzsébet}, booktitle = {Proceedings of the 29th International Symposium on Analytical and Environmental Problems}, unique-id = {34453926}, year = {2023}, pages = {161}, orcid-numbers = {Nyergesné Illés, Erzsébet/0000-0002-2901-9616} } @CONFERENCE{MTMT:34407456, title = {Effects of oil composition and CNT functionalizaton on the membrane filtration of oily wastewaters with TiO2/(f)CNT composite-coated PVDF membranes}, url = {https://m2.mtmt.hu/api/publication/34407456}, author = {Fazekas, Ákos Ferenc and Gyulavári, Tamás and Pap, Zsolt and Bodor, Attila and Laczi, Krisztián and Perei, Katalin and Nyergesné Illés, Erzsébet and László, Zsuzsanna and Veréb, Gábor}, booktitle = {XXIX.
