TiO₂/Ti Electrode Preparation, Characterization and its Photoelectrocatalytic Stability

Abstract:

TiO2/Ti electrode, photoelectrocatalysis (PEC), rotating disk reactor, dye. Abstract: In this work, TiO2/Ti electrode was prepared by sol-gel method and its character was investigated by field emission scanning electron microscope (FESEM), X-ray reflection diffraction (XRD) spectra, UV-Vis diffuse reflection absorption spectra and photoelectro-response analysis. FESEM and XRD analysis demonstrates the TiO2 particles were uniform, about 50 nm and almost anatase, UV-Vis diffuse reflection analysis demonstrates the absoption fringe of TiO2 was 400 nm, and photoelectro-response analysis demonstrates the photoelectro-response capability of the photocatalyst was evident and decreased with the dye solution concenstrate increased. The results of stability and reproducibility of TiO2/Ti electrode demonstrates repetition of both multi-runs of mono-electrode and mono-run of multi-electrodes was excellent, which indicates TiO2/Ti electrode prepared by sol-gel method can degrade dye wastewater high-effectively and stably.
