摘要: Pt金属是直接甲醇燃料电池(DMFC)常用的催化剂.为了尽可能减少Pt金属用量,提高Pt的分散度,人们总是选择具有高表面积的基质,如石墨、碳黑、活性碳、分子筛、质子交换膜等,作为Pt金属的载体.

Abstract: carbon-nanotubes with diameters ranging between140~220nm was synthesized with chemical vapor deposition method, and treated using nitric acid as oxidant. Pt/C catalysts were prepared using untreated and treated carbon-nanotubes as supports, respectively. TEM and FT-IRdifferential spectra showed that treated carbon-nanotubes become short and possess more oxygen-containing surface groups. The electrochemical studies indicated that the Pt/treated carbon-nanotubes catalyst possessed much higher electrocatalytic activity for the oxidation of methanol than that of the Pt/untreated carbon-nanotubes catalyst.
Keywords: carbon-nanotubes  platinum catalyst  methanol
