The advancement of novel metal–organic frameworks (MOFs) catalysts bears practical significance for improving photoelectrochemical (PEC) water splitting performance. A MOF glass catalyst was synthesized via a melting glass-forming cobalt-based zeolitic imidazolate framework (Co-a_gZIF-62). Introducing the MOF glass catalyst on various metal oxide semiconductor substrates coupled with NiO hole transport layer constructs the integrated Co-a_gZIF-62/NiO/MO photoanodes. From experimental analyses and density functional theory calculations, Co-a_gZIF-62 can effectively promote charge transfer and separation, improve carrier mobility, accelerate the kinetics of oxygen evolution reaction, and thus improve PEC performance.
