Doping photocatalyst for water splitting - EurekAlert
A comprehensive look at doping photocatalysts in water splitting under visible light is presented. Doping to regulate the band structure of Bi-based composite oxides achieves overall water splitting. Performance improvements in hydrogen production are made by doping to control the photocatalyst's micro-morphology (selectively exposing high-activity crystal facets) and surface properties (surface phosphorization). A multi-local gradient doping technique constructs a three-dimensional potential well, efficiently driving charge separation, extending photogenerated carrier lifetimes, and enhancing photocatalytic water splitting performance.
