Tóm tắt

AbstractGraphitic C3N4 (g‐C3N4) is used as a low‐cost organic oxygen evolution reaction (OER) electrocatalyst. The integration of ultrathin g‐C3N4 nanosheets with graphene leads to g‐C3N4/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.
