Abstract

Abstract : A combination of liquefaction–carbonization–graphitization technology innovation is used to prepare graphitic carbon materials from corn straw as an inexpensive woody biomass feedstock. Abstract : Corn straw-based graphitized carbon was prepared by carbonization and a catalyzed graphitization method using corn straw as the raw material and catalytic liquefaction technology. A mixture of polyethylene glycol (PEG200) compounded with glycerol in the mass ratio of 7 : 3 was used as the liquefied agent, meanwhile 0.3 g of hydroxydiethylidene glycolic acid acted as the liquefied catalyst. The liquefied products were treated via carbonization and graphitization processes to form graphitized carbon. The graphitized carbon showed better graphitization, a microscopic lamellar structure, and smaller defects, when the carbonized temperature was 600 °C, graphitization temperature 850 °C, and the catalyst was ferric acetylacetonate at a concentration of 7.0 mmol g −1 . The corn straw-based graphitized carbon yield reached 22.20%.
