摘要(Abstract)：

为了设计和开发一种经济高效的析氧反应（OER）催化剂，采用化学氧化法和水热法等方法，使用聚吡咯（ppy）对还原氧化石墨烯（rGO）进行功能化改性，再结合磷化镍（Ni_2P），制备Ni_2P/ppy/rGO催化剂。运用X射线衍射（XRD）、扫描电子显微镜（SEM）和X射线光电子能谱仪（XPS）对材料进行结构和形貌表征，再通过电化学测试研究了催化剂的析氧反应性能。结果表明，Ni_2P/ppy/rGO具有良好的电催化性能，在电流密度为10 mA·cm~(-2)时，需要的过电势（258 mV）较小，表现出比ppy/rGO(319 mV）、Ni_2P/ppy(323 mV）更好的电催化析氧性能。Ni_2P/ppy/rGO催化剂相应的塔菲尔斜率（74.0 mV·dec~(-1)）也较小，表明其在析氧反应中具有较好的催化动力学性能。
