Interactive oxidation of photoelectrocatalysis and electro-Fenton for azo dye degradation using TiO?¡VTi mesh and reticulated vitreous carbon electrodes

Abstract

A crystallized TiO?thin film was prepared by electrolytic anodization of a pure Ti mesh in sulfuric acid¡Vphosphoric acid¡Vhydrogen peroxide and hydrofluoric acid¡Vsodium fluorid¡Vhydrogen peroxide electrolyte solutions. The TiO?particles directly grown on the Ti mesh surface had the regular anatase crystal structure. The TiO?thin film showed a multiporous structure and the mean micropore size was about 260 nm. The azo dye orange-G degradation reac
