Toward a rational photocatalyst design: a new formation strategy of co-catalyst/semiconductor heterostructures via in situ exsolution

Abstract

A new “post-growth” approach to implant metal sulfide nanodots (<5 nm) with high population and uniform dispersion into a semiconductor parent matrix was reported. The encapsulation modality of nanodot co-catalysts grants enhanced visible light absorption and photocatalytic performance, which provides another route for hetero-architecture materials design.
