摘要：

Exploration of appropriate photocatalysts for visible-light-driven organic synthesis is of great importance. Here we design and construct a two-dimensional hierarchical In2S3/MoS2 composite as an excellent and reusable photocatalyst for Aza-Henry reaction. The dahlia-flower-like In2S3 nanostructures are homogeneously grown on both sides of the two-dimensional MoS2 nanosheets via a hydrothermal reaction. The as-prepared two-dimensional hierarchical In2S3/MoS2 composite exhibits higher photocatalytic performance than pure In2S3. The hierarchical heterostructure can enhance the light absorption in the visible region, facilitate the separation of the photo-induced electron hole pairs, offer rich active sites for photoredox reactions and promote the generation and migration of the center dot O-2(-) and h(+). Profiting from these compositional and structural features, the two-dimensional hierarchical In2S3/MoS2 composite shows remarkably enhanced photocatalytic performance and good stability.
