Porous carbon and method of manufacturing same

摘要

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 varnish 1 as a carbon precursor, magnesium oxide 2 as template particles, and chloroplatinic acid 6 as 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 carbon 3 containing the platinum particles 7; and washing the resulting carbon 3 with a sulfuric acid solution added at a concentration of 1 mol/L to completely dissolve MgO away.

1. A porous carbon having a carbonaceous wall constituting an outer wall of mesopores, the carbonaceous wall forming a three-dimensional network structure, and micropores each formed in a position in the carbonaceous wall that faces the mesopores, characterized in that:
metal particles are dispersed in the carbonaceous wall, and at least a portion of the metal particles is buried in the carbonaceous wall in such a state that a portion of the surface of the particle is exposed in the micropores, thereby inhibiting oxidization of the metal particles.
