Preparation of NiCoP-decorated g-C3N4 as an efficient photocatalyst for H2O2 production

The development of high-efficiency economic photocatalyst for H2O2 production is of great significance for renewable energy technologies. Here, we use a successive in situ growth and phosphating method successfully prepared NiCoP/g-C3N4 composite photocatalyst. NiCoP was uniformly dispersed in the form of nanoparticles on the surface of g-C3N4 nanosheet as a cocatalyst. The obtained NiCoP/g-C3N4 composite showed excellent performance in photocatalytic production of H2O2, which was due to NiCoP, has a better electronic conductivity to efficiently transfer charge, improves charge separation efficiency and enhances visible light absorption. This study can provide an effective theoretical basis for the design of bimetallic phosphide modified photocatalysts for photocatalytic production of H2O2.
