Photoelectrocatalytic water splitting is an effective way to utilize the solar energy to solve the energy shortage. The valence band edge of WO3located at ∼3 Vvs.normal hydrogen electrode (NHE), which can offer enough potential to kinetically oxidize water for oxygen evolution reaction. However, water oxidation reaction kinetics is sluggish when only WO3is used as the photoanode. It is highly desirable to use cocatalyst to promote the kinetics. MnOxloaded on the WO3photoanode through photodeposition methods improves the photoelectrochemical water oxidation performance. A maximum photocurrent density of composite photoanode is achieved with a deposition time of 3 min, which is higher than that of pristine WO3photoanode around 40%. MnO2is not only a cocatalyst for water splitting but also for improving oxidation selectivity. We tried to use two means to load MnOxon WO3photoanode material. It is observed that loading a moderate amount of MnOxon the WO3by photodeposition can promote the performance of the WO3photoanode.
