Paper-Based N-Doped Carbon Films for Enhanced Oxygen Evolution Electrocatalysis.

for the assembly of graphene and graphitic carbon nitrate (g-CN) ultrathin nanosheets. The resultant materials, which possess highly active centers, rich porosity, and 3D conductive networks, can catalyze the oxygen evolution reaction with competitive activity and much better durability compared to the benchmark noble metal electrocatalysts (IrO).
