析氢反应（HER）和析氧反应（OER）在将来自可再生能源的能量转化为化学能中起关键作用。高效、稳健且廉价的电催化剂对于在低过电位下以高速率驱动这些反应并使能量损失最小化是必要的。最近，衍生自混合金属膦酸盐化合物的电催化剂已经显示出对HER或OER的高活性。在这里，我们回顾利用金属膦酸盐配位网络和金属有机框架作为前体/模板过渡金属磷化物，磷酸盐，或羟基氧化物在碱性溶液中原位生成，和它们的电催化性能HER或OER。
The hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) play key roles in the conversion of energy derived from renewable energy sources into chemical energy. Efficient, robust, and inexpensive electrocatalysts are necessary for driving these reactions at high rates at low overpotentials and minimize energetic losses. Recently, electrocatalysts derived from hybrid metal phosphonate compounds have shown high activity for the HER or OER. We review here the utilization of metal phosphonate coordination networks and metal-organic frameworks as precursors/templates for transition-metal phosphides, phosphates, or oxyhydroxides generated in situ in alkaline solutions, and their electrocatalytic performance in HER or OER.
