NOVELTY - A nitrogen-phosphorus-doped carbon material shows characteristic peak area between 394ev and 400.5ev in XPS analysis, where the characteristic peak areas between 393-410ev are more than 80% and preferably 90%. USE - Nitrogen-phosphorus doped carbon material e.g. nitrogen-phosphorus-doped graphene, nitrogen-phosphorus-doped conductive carbon black, and nitrogen-phosphorus-doped carbon nanotubes used in manufacture of platinum carbon catalyst used as catalyst of oxygen reduction reaction in electrochemical field such as fuel cell and metal air cell and in hydrogen fuel cell as anode and/or cathode (all claimed). ADVANTAGE - The nitrogen-phosphorus-doped carbon material has excellent mass ratio activity, electrochemical stability and stability, and provides platinum-carbon catalyst with excellent performance and high platinum-carrying amount. The aqueous phase reduction process for the production of the platinum carbon catalyst is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparation of phosphorus-doped carbon material involves (s1) contacting the carbon material with a phosphorus source and a nitrogen source, treating for 0.5-10 hours at 300-800 ℃ in inert gas(s2)loading platinum by taking the nitrogen-phosphorus doped carbon material obtained in the step (s1) as a carrier. platinum-carbon catalyst has N1s spectral peak of XPS analysis, the characteristic peak area between approximately between 399ev and 400.5ev accounts for approximately between 390ev and 410ev are more than 80% and preferably 90% or more.
