Preparation of Crystallized and Mesoporous Carbon by Nickel-catalyzed Carbonization of Wood

Abstract

Abstract Char composed of crystallized carbon (T component) and enriched with mesopore was obtained by carbonization of nickel-loaded wood at 850 and 900 °C for 1 h in a flow of nitrogen, although the corresponding treatment of wood without nickel gave amorphous and microporous carbon. This also disclosed a close relationship between the production of T component and the formation of mesopore. The crystallized and mesoporous wood carbon that can possess a double function of electroconductivity adequate for electromagnetic shielding and adsorption capacity comparable to that of coal-derived activated carbon is a promising high-quality carbon electrode material.
