Improved photoelectrochemical activity for tetragonal BiV0.8Mo0.2O4 fabricated by hydrothermal synthesis is reported in the present study. The enhanced water oxidation efficiency is attributed to the formation of cation vacancies (Bi5+)/oxygen interstitials due to high amount of Mo doping. Efficient...
