Insights into the photocatalysis mechanism of the novel 2D/3D Z-Scheme g-CN/SnS heterojunction photocatalysts with excellent photocatalytic performances.

A novel 2D/3D Z-scheme g-CN/SnS photocatalyst was successfully fabricated via self-assembly forming 3D flower-like SnS microspheres on the surface of the 2D g-CN nanosheets. The photocatalytic performances of the samples were systematically explored through catalytic reduction of Cr and oxidation of Bisphenol S (BPS) under the illumination of visible light, and the photocatalytic degradation pathway of BPS was also proposed based on the degradation products confirmed by GCMS. Among the as-prepared samples, 0.
