Abstract | Water oxidation catalysts have been usually used to enhance the charge injection efficiency of WO3 anodes. Herein, we simultaneously improve the charge separation efficiency and charge injection efficiency, as well as the oxidation selectivity of WO3 for photoelectrochemical water oxidation by loading CoOx nanoparticles in a neutral electrolyte. The produced oxygen is monitored by a Clark electrode, which shows a high Faradaic efficiency on CoOx/WO3. In an effort to gain insight into the role of CoOx on the high Faradaic efficiency, the rotating ring–disk electrode system was used to detect the products of the CoOx/WO3 heterojunction in the photoelectrochemical water oxidation process. The results show that the loading of CoOx nanoparticles can improve oxidation selectivity of WO3 and therefore improve the Faradaic efficiency of WO3. |
