Constructing a multicomponent junction for improved visible-light photocatalytic performance induced by Au nanoparticles

Abstract

Au induced visible-light photocatalytic performance is, for the first time, demonstrated to be effectively enhanced by a proper construction of a junction nanostructure. A study of the ˙O₂⁻ and H₂O₂ radicals indicates the efficient electron transfer across the Au–SrTiO₃–TiO₂ composite facilitated by the junction effect is responsible for the enhancement, and ultimately promotes the photocatalytic process.
