The role of molecular oxygen (O2) in the photocatalytic decomposition of a model compound, acetic acid, was studied using suspensions and electrodes of metal oxide particles, titanium(IV) oxide (TiO2) or tungsten(VI) oxide (WO3). Results for photocurrent efficiency in photoelectrochemical measurements revealed that reaction of O2 with radicals liberated by positive holes increases the overall rate of photocatalytic oxidative decomposition of acetic acid.
