【摘要】 对绿色、高效能源储存装置日趋强烈的需求，使得用于清洁能源转换的先进技术获得了研究者的密切关注。具有环境友好、高能量转换效率等优势的燃料电池是传统能源转换装置极具希望的替代品。然而，工业催化界中商业化程度高的Pt体系催化剂存在成本高、稳定性差和抗毒化能力弱等问题，限制了燃料电池的进一步发展。开发储量丰富、成本低廉且性能优异的非Pt体系氧还原（ORR）催化剂是降低燃料电池成本，促进其大规模应用的有效途径。对此，结合近10年来国内外研究成果，系统介绍了当前各类非Pt体系ORR催化剂的研究进展，包括非贵金属基以及非金属基催化剂。同时，针对各类催化剂的优点、不足及改性策略进行了归纳与总结，并对未来ORR电催化剂的发展提出挑战、做出展望。更多还原

【Abstract】 With the increasing demand for green and efficient energy storage devices, advanced technologies for clean energy conversion have attracted close attention from researchers. Fuel cells with environmental friendliness and high energy conversion efficiency are promising alternatives to traditional energy sources.However, Pt catalysts with high commercialization degrees in the industrial catalysis field have some problems, such as high cost, poor stability and weak anti-toxicity ability, which limits the further development of fuel cells. The development of non-Pt oxygen reduction reaction(ORR) catalysts with abundant reserves, low cost and excellent performance is an effective way to improve the efficiency of fuel cells. In this paper, based on the research results at home and abroad in recent years, various types of non-Pt system ORR catalysts, including non-precious metal and non-metal catalysts, are systematically introduced. The advantages, disadvantages and modification strategies of various catalysts are summarized, and challenges and prospects for the development of ORR electrocatalysts are put forward.更多还原
