Tandem Photocatalysis of Graphene-Stacked SnS₂ Nanodiscs and Nanosheets with Efficient Carrier Separation.

ABSTRACT: Being an optical semiconductor, tin disulfide (SnS₂) attracts increasing interest in the fields of heterogeneous photocatalysis and photovoltaics. However, support from a graphene sheet in the form of a nanocomposite is expected to increase the stability and effectiveness of a SnS₂ material in potential applications. We report here novel nanocomposites of graphene-oxide-stacked hexagonal-shaped pristine SnS₂ nanodiscs (NDs of two different sizes) and nanosheets synthesized using an in situ one-pot hydrothermal synthesis process and the application of the nanocomposite as an efficient heterogeneous photocatalyst. The as-synthesized morphology-oriented nanoparticles and nanocomposites were comprehensively characterized, and finally, excellent photocatalytic a
