TiO2/Ti electrode preparation, characterization and its photoelectrocatalytic stability

摘要

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,bW-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.
