摘要
电子产品的不断发展使得人们对电池的要求越来越高,乙醇燃料电池因环保、高能、易存储等诸多优势备受关注。但其商业化之路仍面临困境,制备低成本、高活性、抗毒性的催化剂是解决问题的关键。脱合金方法简单易操作,可构筑不同纳米结构的金属复合物材料,发挥各活性组分的协同催化效应。本文着眼于乙醇燃料电池的阳极氧化,从脱合金前驱体制备、脱合金方法、催化金属种类、催化剂元素数目四个方面,阐述了近年来乙醇燃料电池阳极催化剂的研究进展,分析了不同催化剂的催化机理及优缺点,并对乙醇燃料电池未来发展及大规模应用提出了展望。
With the increasing development of electronic products,the requirement for cells is higher.The direct ethanol fuel cells attract intense attention for environmental benignity,high energy and easy storage.However,its commercialization avenue encounters a dilemma.The key solutions are producing low-cost,high-activity and antitoxic catalysts.Dealloying is a facile method.It can fabricate various nano-structures of metal compounds and realize the synergistic effect of all active ingredients.In this paper,the manufacture of precursors,methods of dealloying,kinds of metal catalysts and numbers of catalyst elements with respect to anode oxidation were reviewed.The mechanisms,advantages and disadvantages of different catalysts were analyzed.The future research trend and large-scale application were also prospected.
