| 摘要 | In this work, a H2O2-treated indium oxide (In2O3) semiconductor material was prepared. The photoelectrochemical cathodic protection performance and the photoelectrochemical behaviors of the H2O2-treated In2O3 were investigated. Under visible light illumination, the H2O2-treated In2O3 exhibits enhanced photoelectrochemical conversion efficiency ( the photoinduced current density was increased by approximately 50%) and enhanced photoelectrochemical cathodic protection performance (the photoinduced cathodic protection current density was increased by approximately 81.8%). The concentrations of adsorbed oxygen and oxygen vacancy in In2O3 were increased after H2O2 treatment, resulting in the enhancement of visible light absorption activity of the H2O2-treated In2O3. With the increase of the concentration of oxygen vacancy, the Fermi level of In2O3 negatively shifts, which promotes the photoelectrochemical cathodic protection performance of the H2O2-treated In2O3. The increased surface adsorbed oxygen groups is beneficial for capturing the photoinduced electrons, resulting in the promotion of the separation efficiency of the photogenerated electron-hole pairs and the electron transfer capability, and hence leading to the increase of the photoelectrochemical cathodic protection performance of the H2O2-treated In2O3.
