A method of making a microporous carbon material which includes providing a precursor selected from the group consisting of crystalline salts of aromatic sulfonates and nonporous polymeric salts. Prior to carbonization, the precursor is treated by ion exchange or other conventional processes to introduce a metal such as iron, nickel and cobalt into the precursor. Heat treatment of such composite precursors in the temperature range of 350.degree. to 850.degree. C. in an inert oxygen free atmosphere for a sufficient time promotes thermally induced hydrogen abstraction and rearrangement of BSUs which result in the formation of a composite, carbonaceous microporous material which contains a metal component, and has a pore size distribution in the range of about 4-15 .ANG. A. The structural and storage characteristics of the microporous carbon materials are also disclosed.
