Abstract
A porous carbon and a method of manufacturing the same are provided, which can inhibit metal particles from being oxidized and can keep the effect obtained by adding the metal particles for a long period of time by allowing the metal particles to disperse sufficiently. The method is characterized by comprising the steps of: mixing a polyamic acid resin varnishas a carbon precursor, magnesium oxideas template particles, and chloroplatinic acidas a metal salt; heat-treating the mixture in a nitrogen atmosphere at 1000° C. for 1 hour to reduce the chloroplatinic acid into platinum and thermally decomposing the polyamic acid resin to prepare a carboncontaining the platinum particles; and washing the resulting carbonwith a sulfuric acid solution added at a concentration of 1 mol/L to completely dissolve MgO away.
