直接甲醇燃料电池甲醇电氧化催化剂研究的新动向

Research on Methanol Electro-oxidation Catalysts in Direct Methanol Fuel Cell

概述了直接甲醇燃料电池甲醇电氧化催化剂最近的一些研究情况。电化学沉积法和采用有机金属前驱体、有机溶剂中还原金属化合物制备催化剂的方法可以有效地控制催化剂组成、分布、颗粒大小 ;铂 -金属大环化合物对甲醇的电催化氧化具有很好的催化活性 。

Some recent development on methanol electro-oxidation in direct methanol fuel cell are reviewed.The methods of preparing platinum alloy electrocatalysts,such as electrodeposition,using polymetallic precursors and reducing platinum chloride in non-aqueous solution,can effectively control particle size,size distribution and atomic configurations in anode catalysts. Metal macrocycles are active for methanol electro-oxidation;metal carbides and perovskite oxides are non-noble catalysts for possible substitution of noble platinum-based catalysts in direct methanol fuel cell.
