Because the oxygen evolution reaction (OER) process is a rate-determining step for water splitting, it is extremely significant to rationally design and explore highly efficient and durable as well as the low-cost OER electrocatalyst to promote electrocatalytic water splitting. Based on this consideration, herein, for the first time, multi-metal oxides MoO₂/Co₂Mo₃O₈/Fe₂Mo₃O₈ (MCF) compactly anchored N, P-doped carbon matrix (CNT and amorphous carbon derived from cobalt hexacyanoferrate) (MCF/NPCCNT) is fabricated by simply pyrolyzing composite precursor consisted of phosphomolybdic acid, cobalt hexacyanoferrate and CNT under the nitrogen atmospheres. The as-prepared MCF/NPCCNT-40 hybrid catalyst delivers a high OER electrochemical activity with a smaller overpotential of 292 mV at the current density of 10 mA cm^-2 and a lower Tafel slope of 45.9 mV dec^-1, as well as favorable cycle stability in 1.0 M KOH solution, markedly improving the charge transfer efficiency in catalytic processes and preventing the corrosion of the metallic compounds. In addition, the MCF/NPCCNT-40 hybrid catalyst exhibits large mass density of 323.2 A g^-1 at a fixed potential of 1.7 V, which is the highest mass activity towards OER process compared to the other reference samples. The design idea and synthetic strategy of this work can be expanded to design and fabricate other novel, highly effective and low-cost multi-metal oxide anchored N, P-doped carbon matrix based electrocatalysts with greatly improved OER performance.

由于析氧反应（OER）过程是水分解的决定速率的步骤，因此合理设计和探索高效耐用的低成本OER电催化剂以促进电催化水分解非常重要。基于此考虑，本文首次首次采用多金属氧化物MoO ₂ / Co ₂ Mo ₃ O ₈ / Fe ₂ Mo ₃ O ₈（MCF）通过在氮气氛下简单地热解由磷钼酸，六氰铁酸钴和CNT组成的复合前驱体来制备紧密锚固的N，P掺杂碳基体（CNT和源自六氰铁酸钴的无定形碳）（MCF / NPCCNT）。所制备的MCF / NPCCNT-40杂化催化剂具有较高的OER电化学活性，在10 mA cm ^-2的电流密度下具有更小的292 mV的过电势和更低的45.9 mV dec ^-1的Tafel斜率，以及良好的在1.0 M KOH溶液中的循环稳定性，显着提高了催化过程中的电荷转移效率，并防止了金属化合物的腐蚀。此外，MCF / NPCCNT-40杂化催化剂的质量密度大，为323.2 A g ^-1在1.7 V的固定电势下，与其他参考样品相比，这是针对OER过程的最高质量活性。这项工作的设计思想和合成策略可以扩展到设计和制造其他新颖，高效，低成本的多金属氧化物锚定的N，P掺杂碳基碳基电催化剂，并大大提高OER性能。
