Inorganic Photocatalysts for Overall Water Splitting
MetadataShow full item record
Photocatalytic water splitting using semiconductor photocatalysts has been considered as a "green" process for converting solar energy into hydrogen. The pioneering work on electrochemical photolysis of water at TiO2 electrode, reported by Fujishima and Honda in 1972, ushered in the area of solar fuel. As the real ultimate solution for solar fuel-generation, overall water splitting has attracted interest from researchers for some time, and a variety of inorganic photocatalysts have been developed to meet the challenge of this dream reaction. To date, high-efficiency hydrogen production from pure water without the assistance of sacrificial reagents remains an open challenge. In this Focus Review, we aim to provide a whole picture of overall water splitting and give an outlook for future research.
