title: A novel and highly efficient earth-abundant Cu3P with TiO2"P-N" heterojunction nanophotocatalyst for hydrogen evolution from water.
abstract: Semiconductor-based photocatalytic hydrogen (H2) evolution from water is of great importance for solar-to-chemical conversion processes to boost and promote the future hydrogen economy. Here, for the first time, we demonstrate that p-Cu3P coupled with n-TiO2forms a novel hybrid structure which accelerates electron-hole pair separation and transfer for improved photocatalytic H2-evolution activity. The rate of H2evolution of the optimized Cu3P/TiO2(7940 μmol h-1g-1) is 11 times higher than that of bare TiO2, with an apparent quantum efficiency (AQE) of 4.6%. This work may provide more insight into the synthesis of novel phosphide-based hybrid materials with high photocatalytic H2-evolution activity and sufficient stability for solar-to-chemical conversion and utilization.
