主　　题：Oxygen reduction reaction Electrocatalyst Non-precious metal Active site 

摘      要：Metallic cobalt was deposited on acetylene black to synthesize a composite Co/C by chemical reduction method.A platinumfree electrocatalyst Co-N/C（800） for oxygen reduction reaction（ORR） was synthesized by mixing the composite Co/C with urea and heat-treating at 800℃.The results from linear sweep voltammograms indicated that the Co-N/C（800） is active to ***β-Co and cobalt oxides are not the active site of the catalyst Co-N/***,the existence of cobalt facilitated the modification of nitrogen to carbon black and led to the formation of active site of catalyst Co-N/C（800）.
