Abstract

Loading suitable cocatalysts can significantly enhance photocatalytic activity by accelerating photogenerated charge separation and facilitating interfacial redox reactions. Herein, MoP nanoparticles were synthesized in a straightforward phosphorization procedure and then assembled with red phosphorus (RP) as a cocatalyst to construct the MoP/RP coupled photocatalyst. The composite photocatalyst could achieve pure water splitting, with the hydrogen production activity of 427 μmol h^-1g⁻¹ under full-arc irradiation and 247 μmol h^-1g⁻¹ under visible-light irradiation. The enhanced photocatalytic property was attributed to the intimate contact between MoP and RP for efficient spatial separation of photogenerated carriers and improved surface reaction. Meanwhile, H₂O was oxidized into value-added liquid H₂O₂, which could contribute to the safe and convenient separation of photocatalytic products for the practical application.
