Abstract

An effective and general microwave-assisted strategy has been developed for deposition of monodisperse metal sulfide/oxide nanocrystals on the surface of a type of 3D hierarchical flower-like nanostructure to form TiO₂-based metal sulfide/oxide hetero-nanostructures. We choose the as-prepared TiO₂–CdS hetero-nanostructure as an example, which exhibits obviously enhanced photocatalytic activity for the photodegradation of methyl orange (MO) compared with TiO₂ nanoflowers, P25 and pure CdS under visible-light irradiation.
