Graphitic carbon nitride(g-C_3N_4) was synthesized via direct pyrolysis of melamine and its electrocatalysis toward oxygen reduction reaction was studied.The morphology and structures of the products were characterized by scanning electron microscope and X-ray powder diffractometer.It was found that higher pyrolysis temperature resulted in more perfect crystalline structure of the graphitic carbon nitride product.Electrochemical characterizations show that the g-C_3N_4 has electrocatalytic activity toward ORR through a two-step and two-electron process.
