Rare earth element-enhanced TiO2 achieves high-efficiency photocatalytic overall water splitting Photocatalytic water splitting is a clean energy technology that uses sunlight to split water into oxygen and hydrogen in order to produce green hydrogen,a clean fuel,without relying on fossil fuels.The process is driven by a photocatalyst.While titanium dioxide(TiO2)has long been studied as a promising semiconductor for photocatalytic water splitting,its efficiency has been hindered by rapid charge recombination and insufficient charge separation.
