摘要
阳极催化剂活性低是阻碍直接乙醇燃料电池(DEFC)商业化的主要障碍之一。针对石墨烯的特点和乙醇电氧化过程中的问题,综述石墨烯基乙醇电氧化催化剂的研究概况。主要介绍DEFC阳极乙醇的电氧化机理;探寻降低Pt基催化剂成本及防止催化剂中毒的方法;寻找性能较好的乙醇电氧化非Pt基催化剂;总结增加石墨烯载体与催化剂结合力的方法。对石墨烯基乙醇电氧化催化剂的发展进行展望。
The low activity of anode catalyst was one of the main obstacles to the commercialization of direct ethanol fuel cell(DEFC).According to the characteristics of graphene and the problems during ethanol electro-oxidation, the research status quo of graphene based catalysts for ethanol electro-oxidation was reviewed.The electro-oxidation mechanism of ethanol in DEFC anode was mainly introduced.The methods of reducing the cost of Pt based catalysts and preventing its poisoning were explored.Non Pt based catalysts with good performance for ethanol electro-oxidation were found.The methods to increase the adhesion between graphene and catalyst were explored.The development of graphene based catalysts for ethanol electro-oxidation in the future was prospected.
