Trapping [PMo₁₂O₄₀]^3- clusters into pre-synthesized ZIF-67 toward Mo _x Co _x C particles confined in uniform carbon polyhedrons for efficient overall water splitting.

ABSTRACT: Bi-transition metal carbides (BTMCs) are promising in catalytic fields, but the synthesis of small-sized BTMCs remains a challenge. Here, Mo _x Co _x C (mainly below 20 nm in size) confined in uniform carbon polyhedrons (Mo _x Co _x C@C) was synthesized based on trapping [PMo₁₂O₄₀]^3- (PMo₁₂) clusters into pre-synthesized, uniform ZIF-67 (PMo/ZIF-67). The opening of the windows (0.34 nm) of ZIF-67 cages through heating is essential to allow the trapping of PMo₁₂ into the cages. This trapping route provides a new method to successfully combine POMs and MOFs that can not be effectively combined via traditional POMOF-based (simultaneous assembly) routes. It also has
