We synthesized a new microporous organic-inorganic hybrid nickel phosphonate (NiPPA) material under hydrothermal reaction condition without the use of structure directing agent. The microporous NiPPA material was converted to N, P-codoped nickel oxide (NP/NiO) and N, O-codoped nickel phosphide (NO/NiP) following pyrolysis under air and nitrogen atmospheres, respectively. These high surface area materials were subsequently explored as electrocatalysts towards oxygen evolution reaction (OER) in alkaline media. Among the three catalysts, NP/NiO exhibited the highest electrocatalytic activity for OER with an overpotential of 332 mV to reach a current density of 10 mA cm－2 and a low Tafel slope of 65.6 mV dec－1 in 1.0 M KOH solution. Furthermore, the as-prepared NP/NiO catalyst displayed an outstanding stability over a period of 15 h, suggesting the high durability of this catalyst for OER.

我们在热液反应条件下合成了一种新的微孔有机无机杂化膦酸盐（NIPPA）材料，而无需使用结构指导剂。在空气和氮气大气下进行热解之后，将微孔NIPPA材料转化为N，P代码氧化物（NP/NIO）和N，O代码磷化物（NO/NIP）。这些高表面积的材料随后作为涉及氧气培养基中氧气进化反应（OER）的电催化剂探索。在这三种催化剂中，NP/NIO的OER最高电催化活性，超电势为332 mV，达到10 mA CM-2的电流密度，低TAFEL斜率为1.0 M KOH溶液中的65.6 mV Dec-1。此外，预先准备的NP/NIO催化剂在15小时内表现出了出色的稳定性，这表明该催化剂对OER具有很高的耐用性。
