Doping heteroatoms into metal phosphides to modify their electronic structure is an effective method, but the incomplete exposure of active sites its inherent drawback. In this experiment, both Se doping and P vacancies are simultaneously introduced CoP-Fe2P (named CoFe-P-Se) enhance internal reactivity. Benefiting from unique hollow porous derived MOF-on-MOF template, as well enhanced intrinsic activity achieved by defects doping, CoFe-P-Se exhibits a high specific capacitance 8.41 F cm–2 at current density 2 mA when used supercapacitor electrode. When assembled hybrid with activated carbon, energy reaches 0.488 mWh power 1.534 mW cm–2, capacity retention after 5000 charge–discharge cycles 90.65%. As oxygen evolution reaction (OER) electrode, electrode shows low overpotential only 230 mV 10 278 100 cm–2. Additionally, it excellent stability for over 50 h The designed element vacancy engineering in work will provide insight constructing high-performance electrodes.
