In the last decades, titanium dioxide (TiO 2) has been widely researched, because of its applications in photocatalytic environmental pollution removal and in hydrogen generation. Hence, this work deals with the synthesis of titanium dioxide by anodising titanium sheets, however using different cathodes, which may induce differences in the composition and structure of the obtained oxide layers so that these suspected differences can be observed. All specimens were equally thermally treated after anodising to enhance their photocatalytic activity since this step allows the titanium dioxide to crystallise. Their morphology and crystal structure were characterised by X-ray diffraction and FTIR, and optical properties were characterised by ultraviolet-visible absorption spectroscopy. Furthermore, tests of their photocatalytic properties in the degradation of organic dyes were performed in order to have a first evaluation. Indeed, differences in the photocatalytic behaviour of the anodised specimens using different cathodes were found and evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
