Abstract
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.
Claims23
A method for manufacturing a metal-carrying carbonaceous material comprising:
- (a) impregnating a carbonaceous material in an aqueous solution containing a metal-containing compound;
- (b) thermally treating the impregnated carbonaceous material at a temperature at least 600° C. but not higher than the melting point of the metal under vacuum or in the presence of an inert gas, wherein step (a) is conducted under one or more of the following conditions:
- (a1) under vacuum;
- (a2) with stirring;
- and
- (a3) with the presence of a polar solvent in the aqueous solution;
- wherein the metal is selected from the group consisting of:
- silver, cobalt, nickel, zinc, gold, copper, platinum, palladium, iron, and a combination thereof;
- and
- wherein the metal-containing compound is a nitrate compound.
