Preparation of amorphous and crystalline titanium dioxide on FTO: ITS characterization and photo- catalyticeffect on eriochrome black T

Abstract

In this work, thin films of TiO2 were electrodeposited by photocatalytic efficiency of glass materials coated with TiO2 as an additive layer on FTO substrates. We have studied the characterization of TiO2 electrodeposited on FTO by several methods such as cyclic voltammetry, X-ray diffraction (XRD), scanning electron microscopy SEM, the energy dispersive spectroscopy device (EDS) and microscopy atomic force (AFM). The crystalline deposits were used as catalysts for the photocatalytic oxidation of black dye Eriochrome black T, under an irradiation source (UV lamp 365 nm). The results revealed that the dye undergone slight degradation under UV illumination. Using the spectrophotometer measurements, the rate of discoloration was estimated from the residual concentration.
