Multi-functional Au/CdS/Fe3O4/RGO hybrid nanomaterials with enhanced photocatalytic activity

Abstract

A facile and low-cost layer-by-layer technology has been developed to synthesize a multi-functional Au/CdS/Fe₃O₄/reduced graphene oxide (RGO) hybrid nanomaterial. The RGO nanosheets are indispensable, as they act not only as a supporter to hold the multiple components together, but also as an electron acceptor and transporter to efficiently hinder the recombination of the photogenerated electron–hole pairs.
