Fuel cell cathode catalyst

Platinum alloy nanoparticles supported on nitrogen-doped mesoporous carbon (MPC), obtained by a method comprising:

• in a chamber removing moisture from a nitrogen-doped mesoporous carbon material, the nitrogen-doped mesoporous carbon material having one or more pores;
• evacuating the nitrogen-doped mesoporous carbon material to further remove air from the pores;
• applying a vacuum to the chamber;
• delivering precursors comprising platinum, nickel, and copper to obtain a precursor-impregnated nitrogen-doped mesoporous carbon material;
• purging the chamber using a purge gas;
• heating the precursor-impregnated nitrogen-doped mesoporous carbon material to a functional temperature in a range of from 150° C. to 300° C.;
• and
• delivering a functional gas comprising a gas mixture which comprises H2 and CO to the precursor-impregnated nitrogen-doped mesoporous carbon material, the precursors reacting with the functional gas to form shaped platinum alloy nanoparticles within the one or more pores of the nitrogen-doped mesoporous carbon material.
