直接甲醇燃料电池（DMFC）由于具有燃料来源丰富、价格低廉、易于携带储存等优点,近年来一直是世界上许多国家研究和开发的热点[1].但是甲醇具有一定的毒性,因此要想实现DMFC在诸如手机、笔记本电脑以及电动车等可移动电源领域的应用,必须探索寻找新的液体燃料以替代有毒性的甲醇.其中乙醇很易从农作物中大量生产,又无毒,因此很有可能用作为替代甲醇作DMFC的燃料.乙醇的电催化氧化已被众多的研究者从电催化和乙醇燃料电池的角度进行了广泛研究[2-7].其中,对乙醇电催化氧化活性较好的有pt[2-4]、pt-Ru[6-7]、Pt-Pd[5]和Pt-Mo[7]等催化剂.我们研究组报道了用固相反应法制得的Pt催化剂对甲醇氧化的电催化活性要优于用常规液
Direct methanol fuel cell (DMFC) has been the focus of research and development in many countries in the world for its advantages of rich sources of fuel, low cost, and easy storage and storage [1]. However, methanol has certain toxicity and therefore needs to be realized DMFC in mobile power applications such as cell phones, laptops and electric cars must explore the search for new liquid fuels to replace toxic methanol, where ethanol is easily mass-produced from crops and is non-toxic, so it is quite possible As an alternative to methanol as fuel DMFC.The electrocatalytic oxidation of ethanol has been widely studied by many researchers from the perspective of electrocatalysis and ethanol fuel cells [2-7]. Among them, the electrocatalytic oxidation of ethanol is better Catalysts such as pt [2-4], pt-Ru [6-7], Pt-Pd [5] and Pt-Mo [7] have been reported in our group to report that Pt catalysts prepared by the solid- The electrocatalytic activity is better than the conventional liquid
