Light-Harvesting Novel Hierarchical Porous Cu 9 S 5 -MnWO 4 Hybrid Structures in Photocatalytic Oxidative Homocoupling of Alkynes and Amines.

The discovery of light-harvesting materials for use in photocatalytic organic reactions has recently attracted attention, indicating the potential for utilizing renewable energy sources. A hybrid semiconductor (SC)-SC structure, Cu 9 S 5 -MnWO 4 , was synthesized using a simple, efficient method. The novel hierarchical porous Cu 9 S 5 -MnWO 4 hybrid structures were then applied in the photocatalysis of oxidative homocoupling of alkynes and amines. The design of a heterogeneous catalyst based on a porous, SC-SC hybrid structure and low-cost Cu should generate interest in the fabrication and modification of photocatalysts for a wide range of applications.
