氧化石墨制备氮掺杂氧还原反应电催化剂
Prepared electrocatalyst by oxidized graphite for nitrogen doping oxygen reduction reaction
摘要
Abstract
Graphite was oxidized by modified Hummers method.Then the oxidized graphite was reacted with ammonia at high temperature to prepare a non-precious metal catalyst for oxygen reduction reaction (ORR).The structure of catalyst was characterized by FTIR and XRD.The catalytic activity for ORR was evaluated by electrochemical linear sweeping curve method.The results show that there are-OH,-COOH and O-C-O groups formed on the oxidized graphite in the oxidization process.The-COOH and O-C-O groups can react with ammonia to form the catalytic activity sites for ORR under the facilitation of Mn.The resulted catalyst has good stability in acidic solution and good activity for ORR with an onset potential of 0.6 V (vs.RHE).关键词
