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/Co@ NPC) were prepared via an annealing−phosphidation approach and employed as multicomponent cocatalysts to promote the H 2 and H 2 O 2 production performance of g-C 3 N 4 . The photocatalyst with optimal composition (i.e., CoP/ Co@NPC-15/g-C 3 N 4 ) showed the highest H 2 and H 2 O 2 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 Co@N-doped C-decorated g-C 3 N 4 (Co@NC/g-C 3 N 4 ). Such an improvement originated from the efficient separation of electron−hole pairs and enhanced the surface catalytic activity after suitable phosphidation of Co@NC nanoparticles. Our work showed that metal−organic framework-derived metal phosphide/metal nanoparticle composites proved to be promising cocatalysts to boost photocatalytic H 2 and H 2 O 2 production.
