METHOD FOR THE PREPARATION OF POROUS GRAPHITE CARBON WITH HIGH CRYSTALLINITY USING SUCROSE AS A CARBON PRECURSOR

摘要

A method for the preparation of porous graphite carbon with excellent crystallinity from sucrose as a carbon precursor is provided to improve crystallinity and obtain porosity by allowing a metal precursor to induce a catalytic action in the polymerization process and carbonization process of the carbon precursor, thereby increasing the polymerization degree of a polymer and forming a polymer structure facilitating the formation of crystalline carbon. A method for the preparation of porous graphite carbon with excellent crystallinity comprises: a first step of dispersing sucrose, a transition metal precursor, and silica particles into distilled water and hydrothermally treating the sucrose, transition metal precursor, and silica particles to prepare a polymerized polymer; a second step of drying the polymerized polymer obtained after the hydrothermal treatment, and heat-treating the polymerized polymer at 700 to 1500 deg.C under vacuum or an inert gas flow to prepare a complex; and a third step of treating the complex with a fluoric acid or sodium hydroxide solution, and washing and filtering the complex treated with the fluoric acid or sodium hydroxide solution to prepare graphite carbon.
