A hierarchical SnS@ZnIn₂S₄ marigold flower-like 2D nano-heterostructure as an efficient photocatalyst for sunlight-driven hydrogen generation.

ABSTRACT: Herein, we report the in situ single-step hydrothermal synthesis of hierarchical 2D SnS@ZnIn₂S₄ nano-heterostructures and the examination of their photocatalytic activity towards hydrogen generation from H₂S and water under sunlight. The photoactive sulfides rationally integrate via strong electrostatic interactions between ZnIn₂S₄ and SnS with two-dimensional ultrathin subunits, i.e. nanopetals. The morphological study of nano-heterostructures revealed that the hierarchical marigold flower-like structure is self-assembled via the nanopetals of ZnIn₂S₄ with few layers of SnS nanopetals. Surprisingly, it also showed that the SnS nanopetals with a thickness of ∼25 nm couple in situ
