摘要 化石燃料的过度依赖使人类面临着严重的能源和环境挑战,发展可再生绿色高效能源方式已成为当今社会一重大挑战。本文主要围绕Fe/Fe_(4)C@HC复合空心球催化剂的合成、表征及其电催化氧还原应用方面展开研究。采用原位自模板法合成Fe/Fe_(4)C@HC,通过XRD、SEM、TEM、EDS、XPS、BET等检测表征Fe/Fe_(4)C@HC的组成结构和微观形貌,对Fe/Fe_(4)C@HC的构效关系进行探索。电化学测试表明Fe/Fe_(4)C@HC材料具有优越的氧还原电催化性能,在氧还原催化领域具有一定的应用潜力。 The excessive dependence on fossil fuels has made human beings face serious energy and environmental challenges,and the development of renewable,green and efficient energy methods has become a major challenge in today's society.This paper focuses on the synthesis and characterization of Fe/Fe_(4)C@HC composite hollow sphere catalyst and its application of electrocatalytic oxygen reduction.Fe/Fe_(4)C@HC was synthesized by in situ self-template method,and the constituent structure and micromorphology of Fe/Fe_(4)C@HC were characterized by detection of XRD,SEM,TEM,EDS,XPS,and BET,and the structure-activity relationship of Fe/Fe_(4)C@HC was explored.Electrochemical tests show that Fe/Fe_(4)C@HC materials have superior oxygen reduction electrocatalytic properties and certain application potential in the field of oxygen reduction catalysis.
