SnS microflower-graphene (G-SnS) has been successfully prepared by microwave method. Scanning electron microscopy and transmission electron microscopy observations confirm that flower-like SnS composing of numerous nanoplates as building blocks are homogeneously attached onto the surface of graphene. The experimental results show that these nanocomposites have high visible-light photocatalytic activities towards methyl orange (MO). It is believed that the hierarchical nature of the microflower structure and the intimate combination of microflower with graphene are responsible for the enhanced photocatalytic performance.
