摘要

用液相还原法制备碳载Pt(Pt/C)和碳载Pt/WO3(Pt/WO3/C)催化剂.实验表明该催化剂中加入一定量的WO3后,其对甲醇的催化氧化活性和稳定性都有一定提高,并以Pt、W原子比为1∶1的催化剂性能最好.这是由于Pt催化剂中加入了WO3后,其电化学活性比表面积增大,并且降低了对CO吸附强度.

Abstract

The catalysts of Carbon supported Pt(Pt/C) and carbon supported Pt/WO3(Pt/WO3/C) were prepared with liquid phase reduction method.It was found that the catalytic activity and stability of the Pt/WO3/C catalysts were increased with the addition of WO3.When the atomic ratio of Pt and W was 1∶1,the best electrocatalytic performance of the Pt/WO3/C catalyst for the methanol oxidation was obtained.This is attributed to the larger electrochemical surface area of Pt/WO3/C and the weeker adsorption of CO towards the catalyst.

Key words： platinum; tungsten trioxide; electrocatalytic-oxidation; methanol; carbon monoxide
