▎ 摘  要

NOVELTY - Material comprises sulfur-nitrogen-phosphorus-boron-doped graphene, sulfur-nitrogen-phosphorus-boron-doped carbon nanotubes, or sulfur-nitrogen-phosphorus-boron-doped conductive carbon black. The material in the S2P spectrum peaks of its XPS analysis there is only the characteristic peak of thiophene sulfur between 160ev and 170ev. The conductive carbon black comprises EC-300J, EC-600JD, ECP-600JD, VXC72, Black pearls 2000, PRINTEX XE2-B, PRINTEX L6 or HIBLAXK40B2. USE - The material is useful as catalyst of oxygen reduction reaction in electrochemical field e.g. fuel cell and metal air cell. ADVANTAGE - The material has a unique property and a simple preparation method, excellent catalytic performance and carbon corrosion resistance and a higher platinum-carrying amount on the basis of the above objectives. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Doping a carbon material; (2) Preparing material; (3) Platinum carbon catalyst; (4) Preparing carbon catalyst; and (5) Hydrogen fuel cell.
