Designing efficient electrocatalysts for oxygen evolution reaction (OER) is very important for renewable energy storage and conversion devices. In this paper, we introduced a new strategy to synthesize Ni doped Co/NC catalysts (NC is the abbreviation of nitrogen-doped graphitic carbon), which were derived from ZIF-67. All catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and oxygen evolution reaction (OER). The results show that Ni was well doped in the Ni/Co/NC catalysts and the doping of Ni has great influence on the OER activity of Ni/Co/NC catalysts. Among these catalysts, 0.50Ni/Co/NC exhibits the highest OER activity. The onset potential of 0.50Ni/Co/NC is 1.47 V, which is superior than the onset potential of Co/NC (1.54 V), 0.25Ni/Co/NC (1.48 V), 1.00Ni/Co/NC (1.53 V). The excellent OER activity of 0.50Ni/Co/NC catalyst makes its potential to be used on renewable energy storage.

设计用于氧气释放反应（OER）的高效电催化剂对于可再生能源存储和转换设备非常重要。在本文中，我们介绍了一种新的策略来合成ZIF-67衍生的Ni掺杂Co / NC催化剂（NC是氮掺杂石墨碳的缩写）。所有催化剂均通过X射线衍射（XRD），扫描电子显微镜（SEM），透射电子显微镜（TEM）和析氧反应（OER）进行了表征。结果表明，Ni被很好地掺杂在Ni / Co / NC催化剂中，Ni的掺杂对Ni / Co / NC催化剂的OER活性有很大的影响。在这些催化剂中，0.50Ni / Co / NC表现出最高的OER活性。0.50Ni / Co / NC的起始电势为1.47 V，优于Co / NC（1.54 V），0.25Ni / Co / NC（1.48 V），1的起始电势。00Ni / Co / NC（1.53 V）。0.50Ni / Co / NC催化剂出色的OER活性使其有潜力用于可再生能源存储中。
