Abstract
In this work, a novel two-dimensional (2D) layered Fe2P modified Cd0.5Zn0.5S (CZS) nanoparticles composites were successfully developed by an environmentally friendly solvothermal method. The Fe2P-CZS photocatalysts were used for noble-metal-free photocatalytic H2 generation under visible light. The rate of H2 evolution of 13 wt% Fe2P-CZS was 24.84 mmol·g−1·h−1, which was 37.6 times that of CZS (0.66 mmol·g−1·h−1). The formation of the 2D-0D reverse heterojunction in the Fe2P-CZS composite photocatalyst improved the transport and separation of photogenerated electron-hole pairs and optimized the kinetics of hydrogen evolution. Compared with Fe2P particles, the layered Fe2P cocatalysts had higher conductivity and lower hydrogen evolution overpotential.
