TiO2 - rGO composite thin films in Vis-active photocatalysis

Low cost, efficient and Vis-active materials have to be developed and implemented at industrial scale because water re-use is the nowadays priority. The composites with metal oxide matrix and graphene derivative(s) fillers were proved to be viable in photocatalytic processes. Titanium dioxide and reduced graphene oxide can develop Vis-active photocatalytic composites and the interfaces must be optimized targeting efficiency and stability in the aqueous environment. This paper discusses the photocatalytic properties of TiO2 - rGO composite thin films, the efficiencies in degrading the methylene blue standard pollutant, the effect of the filler concentration and the stability of the composites during the photo-degradation processes.
