Graphitic C3 N4 (g-C3 N4 ) is used as a low-cost organic oxygen evolution reaction (OER) electrocatalyst. The integration of ultrathin g-C3 N4 nanosheets with graphene leads to g-C3 N4 /graphene composites with high OER activity and good durability. X-ray photoelectron spectroscopy (XPS) studies suggest that the OER activity results from pyridinic-N-related active sites. This catalyst provides an alternative to OER catalysts based on transition metals.
石墨相氮化碳（g-C3 N4 ）被用作一种低成本的析氧反应（OER）电催化剂。超薄g-C3 N4 纳米片与石墨烯的整合产生了具有高OER活性和良好耐久性的g-C3 N4 /石墨烯复合材料。X射线光电子能谱（XPS）研究表明，OER活性源于与吡啶型氮相关的活性位点。这种催化剂为基于过渡金属的OER催化剂提供了一种替代方案。
