US Patent 7803424 Method for manufacturing metal-carrying carbonaceous material

A method for manufacturing a metal-carrying carbonaceous material is provided. The method comprises immersing a carbonaceous material in a metal-containing aqueous solution under vacuum, with stirring, and/or in the presence of a polar solvent, and then thermally treating the immersed carbonaceous material at a temperature ranging from 120° C. up to a temperature not higher than the melting point of the involved metal under vacuum or in the presence of a protective gas. According to the method, the metal can be effectively carried on a carbonaceous material so as to enhance the applicability of the metal-carrying carbonaceous material.
