摘　　要：在碳纳米管表面电沉积铂,并用抗坏血酸处理铂微粒。采用扫描电子显微镜对催化剂进行形貌表征,并用循环伏安法研究其电化学性能。结果表明:可以在减少铂用量的前提下,得到分散更均匀的铂微粒,并且制备的铂/碳纳米管催化剂对甲醇呈现出较高的电催化氧化活性。Platinum was electrodeposited on carbon nano-tube surface, and the platinum particle was treated in ascorbic acid. The morphology of catalyst was characterized by scanning electron microscopy, and the electrochemical property was investigated by cycle voltammetry method. Results showed that, under the premise of reducing platinum dosage, the obtained platinum particle disperse more evenly, and the prepared platinum/carbon nano-tube catalyst exhibit higher electrocatalysis oxidation activity to methanol.
