发明了一种制备高效甲醇氧化电催化剂的新方法。该方法包括电化学还原溶液中金属离子的吸附而不是游离离子。结果表明，所制备的电催化剂具有较大的电化学活性，铂对甲醇氧化反应的质量活性约为工业催化剂的10倍。该方法为解决直接甲醇燃料电池阳极电催化活性低的问题提供了一种有效的方法。
A novel approach has been invented to prepare efficient electrocatalysts for methanol oxidation. The approach involves electrochemical reduction of adsorption of metal ions instead of free ions in solution. The results showed that the deposited Pt–Ru particles are very thin nanoplatelets, the prepared electrocatalyst has a large electrochemically active surface area and its Pt mass activity toward methanol oxidation reaction is about 10 times higher than that of the commercial catalyst. The novel approach could provide an effective method for solving the problem of low electrocatalytic activity in direct methanol fuel cell anodes.
