Abstract |
Artificial photosynthesis is being intensively investigated for simultaneously storing solar energy as fuels as well as depleting CO2 as a green-house effect gas. Water oxidation is currently considered a major bottleneck in the practical development of solar fuels; thus, intensive efforts have been made to under-stand and achieve efficient water oxidation under visible irradiation using earth-abundant materials. Among them, Fe2O3, BiVO4, and WO3 has been frequently studied and shown promising results. Many strategies have been reported such as the optimization of the electrolyte conditions (i.e., type of ions, pH, etc), the modification of the surface with co-catalysts and hydrogen treatment that prevent surface peroxide accumulation, or enhancing the photogenerated charge separation by coupling Fe2O3, BiVO4, WO3 with other semiconductors as a composite and in complete tandem water splitting systems. Herein, photoelectrochemical cell for water oxidation will be discussed under visible light.
