“…Because of the nature of the anti-microbial testing protocols, it is often difficult to recover the catalyst and perform various cycles of reactions. Recent studies indicated that the photocorrosion can be eliminated by incorporating various additives such as graphene [56][57][58].…”

“…Additionally, the presence of GR in the ZnO-GR composite could enhance adsorption affinity toward MB, which also contributes to improvement of photocatalytic activity of ZnO-GR composite. [82][83][84][85] Consequently, the improvement of photocatalytic activity of ZnO-GR composites is also attributed to other factors such as rising the amount of electron acceptor and transport channel, increasing specific surface area of reactive sites, increasing light harvesting, and so on.

Photocatalytic degradation of organic pollutants is an effective way to overcome environmental pollution. During the past few years, carbon materials have demonstrated great potential to improve photocatalytic performance of ZnO nanomaterials. This review will comment on recent developments of carbon materials (including fullerene, carbon nanotube, and graphene) coupling to improve photocatalytic performance of ZnO for photodegradatation of organic pollutants. The effects of carbon materials on enhancing photocatalytic performance of ZnO include enhancing structure stability, increasing amounts of active sites of pollutant adsorption, boosting electron acceptor formation and transport, enhancing photosensitization, narrowing band gap, etc. Moreover, basic mechanisms how carbon materials enhance photocatalytic activity of ZnO materials are discussed according to the interaction between ZnO and carbon materials. Finally, concluding remarks and current challenges are highlighted with perspectives for future developments of ZnO-based carbon photocatalysts. This review aims at recent research advances on ZnO-based carbon photocatalysts developed for photocatalysis of organic contaminant degradation.

“…Bunun nedeni kompozitteki TiO 2 oranının kütlece %50 olması nedeniyle piklerinin baskın olması ve diğerlerinin piklerinin daha sönük kalmasıdır. +2 öncelikle grafen oksit karboksilat anyonları tarafından tutulmuş ve grafen oksitin yaprakları arasına yerleşmiştir [17]. Bu durum hem ZnO'in kümelenmesini hem de RGO'in katmanlarının yığılmasını önlemiştir.…”

ÖZBu çalışmada, indirgenmiş grafen oksit/çinko oksit (RGO/ZnO) ve indirgenmiş grafen oksit/titanyum dioksit (RGO/TiO 2 ) kompozit malzemeleri hidrotermal yöntem kullanılarak üretilmiştir. PRODUCTION AND APPLICATION OF REDUCED GRAPHENE OXIDE-ZINC OXIDE-TITANIUM DIOXIDE COMPOSITE MATERIAL ABSTRACTIn this study, reduced graphene oxide/zinc oxide (RGO/ZnO) and reduced graphene oxide/titanium dioxide (RGO/TiO 2 ) composite materials were produced by hydrothermal method. RGO/ZnO/TiO 2 composite materials were fabricated by adding TiO 2 nanoparticles to RGO/ZnO composite materials. Graphene oxide (GO) was synthesized by Hummers method. The physical properties of RGO/ZnO/TiO 2 composite materials were analysed by XRD and SEM. Using these obtained composites materials, electrode was fabricated for supercapacitor applications. Electrochemical properties of produced composites were analysed by cyclic voltammetry (CV) and capacitance plots and impedance spectrums of electrodes were determined. As a result of the calculations, specific capacitance values were found to be 3.29 F/g, 19.58 F/g, 24.15 and 14.36 F/g for TiO 2 , RGO/TiO 2 , RGO/ZnO and RGO/ZnO/TiO 2 , respectively.
