摘要：It’s highly desired but challenging to synthesize self-supporting nanohybrid made of conductive nanoparticles with metal organic framework (MOF) materials for the application in the electrochemical field. In this work, we report the preparation of Ni
2P embedded Ni-MOF nanosheets supported on nickel foam through partial phosphidation (Ni
2P@Ni-MOF/NF). The self-supporting Ni
2P@Ni-MOF/NF was directly tested as electrode for urea electrolysis. When served as anode for urea oxidation reaction (UOR), it only demands 1.41 V (vs RHE) to deliver a current of 100 mA cm
−2. And the overpotential of Ni
2P@Ni-MOF/NF to reach 10 mA cm
−2 for hydrogen evolution reaction HER was only 66 mV, remarkably lower than Ni
2P/NF (133 mV). The exceptional electrochemical performance was attributed to the unique structure of Ni
2P@Ni-MOF and the well exposed surface of Ni
2P. Furthermore, the Ni
2P@Ni-MOF/NF demonstrated outstanding longevity for both HER and UOR. The electrolyzer constructed with Ni
2P@Ni-MOF/NF as bifunctional electrode can attain a current density of 100 mA cm
−2 at a cell voltage as low as 1.65 V. Our work provides new insights for prepare MOF based nanohydrid for electrochemical application.
