PtRu / C catalyst capable of resisting CO poisoning as well as preparation method and application of PtRu / C catalyst

Abstract

The invention discloses an anti-CO poisoning PtRu / C catalyst as well as a preparation method and application thereof, and belongs to the technical field of fuel cells. According to the preparation method, firstly, the surface of a carbon carrier is modified through cooperation of acid oxidation and high-temperature annealing, then PtRu alloy particles are accurately loaded by combining an ethylene glycol reduction method, and the high-dispersion carbon-loaded PtRu catalyst is obtained; the catalyst prepared in the invention has high hydroxidation reaction catalytic activity and CO poisoning resistance, and can significantly improve the stability and working efficiency of a fuel cell in impurity-containing hydrogen when applied to a fuel cell anode catalytic reaction.
