摘要/Abstract

摘要： 　采用浸渍沉淀法制备Pt/CNTs和Pt/C催化剂,并对其结构及电催化性能进行比较,表征.实验表明,以碳纳米管作催化剂载体可使催化剂的负载量,载体上铂的分散度以及其活性中心大大提高.与Pt/C(JohnsonMatthey)催化剂相比,Pt/CNTs的电化学性能表现出更大的活性.碳纳米管作为阴极材料在质子交换膜燃料电池加氢反应器合成化学品中的作用十分明显.

Abstract: In this paper, Pt/CNTs catalyst was prepared and its electrocatalytic property was studied by obtaining cycling voltammetry curves (C-V) and Tafel curves. In addition, the XRD,XPS and TEM tests were carried out to determine the structure and composition of the catalysts. It can be found that the platinum loading has been increased significantly using a carbon nanotubes support. Dispersion of Platinum was better and gave more active sites. The electrochemical characteristic of Pt/CNTs was also more desirable than that of Pt/C catalyst(Johnson Matthey). In conclusion, carbon nanotubes can played a conspicuous role in "electrogenerative" processes of PEMFC hydrogenation reactor.
