A Study of TiO2Photo-catalyst Modified by Air Electrode

Abstract

Abstract: Anovel composite electrode which has both of the functions of synthesizing H₂O₂and photocatalysis is reported.This double function composite electrode was prepared by loading the photocatalyst TiO₂/Con a novel substrate which can synthesize H₂O₂The porous properties of TiO₂/Cphotocatalysis layer can make the novel carrier synthsizing H₂O₂efficiently.The current efficiency attained a value of 82%(J=15mA/cm²), and the novel carrier made TiO₂gaining an anodic bias which is very important for improving the photocatalytic activity of TiO₂In this novel system, photochemistry and photocatalysis oxidization were combined near the interface of electrode/solution and thus the degradation rate of organic molecules enhanced rapidly.

Key words: TiO₂, Composite electrode, Photocatalysis, Azo dye
