Abstract
A porous, metal-containing carbonaceous material is disclosed which comprises a porous, carbonaceous body, and fine particles of a metal having an average particle size of 1 .mu.m or less and dispersed in the carbonaceous body. The carbonaceous material may be obtained by a method including the steps of: (a) providing finely divided particles of a metal oxide having an average particle size of 1 .mu.m or less; (b) mixing the particles with an organic substance to obtain a mixture; and (c) carbonizing the mixture in a non-oxidizing atmosphere to convert the organic substance into a porous carbonaceous body and to convert the metal oxide particles into elemental metal particles dispersed in the carbonaceous body.
