Composite catalysts combining a metal–organic framework (MOF) with its derivatives have attracted significant attention in electrocatalysis due to their unique properties. In this study, we report the synthesis of Ni-doped Co-1,4-benzenedicarboxylate (defined as Co3Ni1BDC) via straightforward solvothermal method, aiming enhance oxygen evolution reaction (OER) activity. The introduction Ni modulated electronic structure, yielding high catalytic activity an overpotential (η100) 300 mV and excellent stability for OER. Co3Ni1BDC material was further encapsulated Co2P nanoparticles controlled phosphating annealing process, forming hybrid electrocatalyst (Co3Ni1BDC@Co2P) boost hydrogen (HER) performance. Co3Ni1BDC@ exhibited superior HER performance low overpotentials η10 = 20 η100 127 mV, outperforming precursor. An alkaline electrolyzer assembled Co3Ni1BDC//Co3Ni1BDC@Co2P achieved cell voltage 1.70 V at current density mA cm−2. This work provides valuable idea designing efficient electrocatalysts overall water splitting.
