A composite catalyst includes a carrier and noble metal particles supported by the carrier, wherein the carrier is a nitrogen-doped porous carbon composite material having a plurality of passages. The nitrogen-doped porous carbon composite material can include a nitrogen-doped porous carbon material and a plurality of metal oxide particles. The plurality of metal oxide particles can be uniformly distributed in the nitrogen-doped porous carbon material. The plurality of metal oxide particles can be partially exposed through the plurality of passages. The noble metal particles can be tightly combined with the exposed metal oxide particles to achieve recombination. And the noble metal particles can be at least one of Pd metal particles, Pt metal particles, Ru metal particles, Rh metal particles, Ir metal particles, Au metal particles, or a combination thereof.
