▎ 摘  要

NOVELTY - The sulfur nitrogen phosphorus doped carbon material has, in S2P spectral peak analysis, only a characteristic peak of thiophene type sulfur between 160ev and 170ev. USE - Sulfur nitrogen phosphorus doped carbon material e.g. sulfur-nitrogen-phosphorus doped graphene nanotube or sulfur-nitrogen-phosphorus doped conductive carbon black, used as electrode material in electrochemistry and for platinum carbon catalyst (claimed) used in proton exchange membrane fuel cell (PEMFC). ADVANTAGE - The sulfur-nitrogen-phosphorus-doped carbon material has a unique property and a simple preparation method. It improves the carbon corrosion resistance of the platinum carbon catalyst on the basis of the carbon material. It provides a platinum-carbon catalyst having a more excellent comprehensive performance and a higher platinum-carrying amount. It has good mass ratio activity and ECSA, and it obviously improves the anti-carbon corrosion performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for doping a carbon material; (2) a platinum carbon catalyst comprising a carbon carrier and a platinum metal loaded on it, where the carbon carrier is a sulfur nitrogen phosphorus doped carbon material; (3) preparation method of the catalyst; and (4) a hydrogen fuel cell.
