摘　　要：析氧反应作为电催化水解半反应一直以来都是能源转换领域的研究热点之一。本研究使用邻菲罗啉和2,6-吡啶二甲酸作为配体与钴离子配位形成单核钴基配合物作为前驱体,在氮气气氛下通过低温热解(300~500℃)反应得到Co和氮共掺杂碳的纳米催化剂Co-N-C。同时,利用红外、XRD、Raman等基本表征手段证明Co-N-C纳米材料的形成。电化学测试结果表明300℃时,热解产生的Co-N-C纳米材料有最好的OER催化活性,过电势能为322 mV。为设计新型非贵金属OER反应催化剂提供了一种新的思路。The oxygen evolution reaction,as a critical half-reaction in electrocatalytic water splitting,has consistently been a focal point in energy conversion research.In this paper,phenanthroline and 2,6-pyridinedicarboxylic acid were used as ligands to coordinate with cobalt ions to form mononuclear cobalt-based complexes as precursors.Co and nitrogen o-doped carbon nano catalysts Co-N-C were obtained by low-temperature pyrolysis(300~500℃)under nitrogen atmosphere.At the same time,the formation of Co-N-C nanomaterials was proved by IR,XRD,Raman and other basic characterization methods.The electrochemical test results show that the Co-N-C nanomaterials produced by pyrolysis have the best OER catalytic activity at 300℃,and the overpotential energy is 322 mV.This offers a novel approach to design next-generation non-precious metal catalysts for the OER process.
