Abstract

In this paper, using carbon nanotubes (CNTs) as the carrier, a new type of heterogeneous material Pt-PdNiOx/CNTs was prepared by impregnation reduction method. By means of XRD, TEM, XPS and electrochemical analysis, Pt-PdNiOx/CNTs catalyst of the structure and in the methanol oxidation catalytic mechanism are studied and analyzed the relationship between the structure and properties. The results show that with the increase of Ni content, the size of Pt-PdNi/CNTs catalyst particles was decreased. The average particle diameter of Pt-PdNi / CNTs was 2.4 nm. NiOx protected the relative content of Pt0 activity center, so that zero-valent Pt content in Pt-PdNi / CNTs reached 75.3%. This greatly improved the Pt-PdNiOx / CNTs catalyst anti-poisoning ability and catalytic properties.
