Abstract
A platinum-on-carbon catalyst, a preparation method therefor and the use thereof are provided. Among S2P spectral peaks thereof analyzed by means of XPS between 160 eV and 170 eV, the area of characteristic peaks (preferably a characteristic peak of thiophenic sulfur) located between 162 eV and 166 eV is more than 92%, or more than 95%, or more than 98%, or even only the characteristic peaks (preferably the characteristic peak of thiophenic sulfur) located between 162 eV and 166 eV. A carrier of the platinum-on-carbon catalyst is sulfur-doped conductive carbon black. The carrier of the platinum-on-carbon catalyst, i.e. conductive carbon black, is modified, and by controlling the doping form of the doping element, the mass specific activity and the electrochemical active area of the platinum-on-carbon catalyst are significantly improved. The stability and carbon corrosion resistance of the platinum-on-carbon catalyst can also be improved.
