摘要
Artificial photosynthesis involves the conversion of solar energy, water, and CO2into chemical fuels and oxygen. One of the most challenging steps is the production of oxygen from water oxidation, as it involves multi-electron and proton transfer processes. Recently, dye-sensitized photoelectrochemical cells （DSPECs） have been widely investigated as the devices to attain the goal of water oxidation. Generally, these devices are comprised of a wide band gap semiconductor, typically TiO2or SnO2, a molecular chromophore as a sensitizer, and a water oxidation catalyst （WOC）.
