In situ thermal-assisted loading of monodispersed Pt nanoclusters on CdS nanoflowers for efficient photocatalytic hydrogen evolution
Abstract
Monodispersed Pt nanoclusters have been loaded on the CdS nanoflowers by an in situ thermal-assisted method. The as-prepared Pt-CdS composites possess a high proportion of metallic Pt0. The co-existence of Pt2+ in Pt nanoclusters help to suppress the undesirable hydrogen back-oxidation. The Pt-CdS composites show a superior photocatalytic hydrogen production rate.
