The construction of multicomponent cocatalysts to promote charge transfer and separation is a promising strategy for enhancing the photocatalytic reduction reaction activity. Herein, zeolitic imidazolate framework-67-derived CoP/Co nanoparticles enveloped by N,P-doped C (CoP/[email protected]) were prepared via an annealing–phosphidation approach and employed as multicomponent cocatalysts to promote the H₂ and H₂O₂ production performance of g-C₃N₄. The photocatalyst with optimal composition (i.e., CoP/[email protected]/g-C₃N₄) showed the highest H₂ and H₂O₂ production performance with rates of 3.74 and 9.40 μmol h^–1, respectively, which were about 2.3 and 5.6 times larger than that of unphosphated [email protected]ped C-decorated g-C₃N₄ ([email protected]/g-C₃N₄). Such an improvement originated from the efficient separation of electron–hole pairs and enhanced the surface catalytic activity after suitable phosphidation of [email protected] nanoparticles. Our work showed that metal–organic framework-derived metal phosphide/metal nanoparticle composites proved to be promising cocatalysts to boost photocatalytic H₂ and H₂O₂ production.
