A method for forming a substantially uniform dispersion of a metal or metal oxide in a porous carbon matrix, comprising: forming a uniform co-crystallite from an aromatic carboxylic or sulfonic acid, phenol, thiol, aromatic amine or salt of any thereof and from a salt or complex of a transition meta

A method for forming a substantially uniform dispersion of a metal or metal oxide in a porous carbon matrix, comprising: forming a uniform co-crystallite from an aromatic carboxylic or sulfonic acid, phenol, thiol, aromatic amine or salt of any thereof and from a salt or complex of a transition metal or metal from Groups IIIA, IVA or VA of the Periodic Table of Elements; forming a uniform powdered mixture of the co-crystallite and an alkali metal hydroxide; pyrolyzing the powdered mixture in an inert atmosphere at a temperature in the range of from about 400°C. to about 980°C. to form the carbon matrix having the metal or metal oxide substantially uniformly dispersed therein; and separating unreacted inorganic material and inorganic reaction products, other than the dispersed metal or metal oxide, from the carbon matrix to form the porous carbon matrix end product. The method of claim 1 wherein (1) a solution of both of (a) the aromatic carboxylic or sulfonic acid, phenol, thiol, aromatic amine or salt of any thereof and (b) the salt or complex of the transition metal or metal from Groups IIIA, IVA or VA or (2) a solution of the aromatic carboxylic or sulfonic acid, phenol, thiol, aromatic amine or salt of any thereof and a solution of the salt or complex of the transition metal or metal from Groups IIIA, IVA or VA are spray-dried to form the co-crystallite. The method of claim 1 wherein the porous carbon matrix is active carbon having a BET surface area of at least 800 square meters per gram and a bulk density of at least 0.1 gram per cubic centimeter.
