Abstract
A platinum-carbon catalyst, a preparation method therefor and an application thereof are provided. Among Nspectral peaks of the XPS analysis of the platinum-carbon catalyst, except for the presence of characteristic peaks between 399 ev and 400.5 ev, there are no other characteristic peaks between 395 ev and 405 ev; and a carrier of the platinum-carbon catalyst is nitrogen doped conductive carbon black. The carrier conductive carbon black of the platinum-carbon catalyst is modified, and by means of controlling the doping form of a doping element, the mass specific activity and electrochemical area of the platinum-carbon catalyst are significantly improved; further, the stability of the platinum-carbon catalyst and the ability to resist carbon corrosion may also be improved. A method for preparing the platinum-carbon catalyst is also provided.
