金属酸化物，及びリン酸塩を骨格に有する新規メソ多孔体の合成と応用

在不使用结构导向剂的条件下，在水热反应条件下合成了一种新型微孔有机-无机杂化磷酸镍(NiPPA)材料。微孔NiPPA材料在空气和氮气气氛下热解后分别转化为N，P共掺杂的氧化镍(NP/NiO)和N，O共掺杂的磷化镍(NO/NiP)。这些高比表面积材料随后被探索作为碱性介质中析氧反应(OER)的电催化剂。在三种催化剂中，Np/NiO表现出最高的OER电催化活性，在1.0M KOH溶液中，过电位为332 mV，电流密度为10 mA cm-2，Tafel斜率为65.6 mV dec-1。此外，所制备的Np/NiO催化剂在15h内表现出优异的稳定性，表明该催化剂具有较高的OER稳定性。

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.
