▎ 摘　　要

The reduced graphene oxides (rGO) loaded-ZnS/CuS heteronanostructures have been successfully prepared for the first time. Scanning electron microscopy and transmission electron microscopy observations confirm that ZnS/CuS heteronanostructures are decorated on the rGO. The experimental results reveal that these novel nanostructures exhibit a visible-light photocatalytic activities for methyl orange (MO) dye degradation. The high visible photocatalytic performances are attributed to photoinduced interfacial charge transfer in the heteronanostructures and their further separation and transfer by rGO. This new nanostructure is expected to show considerable potential applications in water purification as well as optoelectronic fields at a large scale. (c) 2013 Elsevier B.V. All rights reserved.
