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 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. The corn straw-based graphitized carbon yield reached 22.20%.
以玉米秸秆为原料，采用催化液化技术，通过碳化和催化石墨化方法制备了玉米秸秆基石墨化碳。以质量比为7:3的聚乙二醇（PEG200）与甘油的混合物作为液化剂，同时0.3 g羟基二亚乙基乙醇酸作为液化催化剂。将液化产物进行碳化和石墨化处理以形成石墨化碳。当碳化温度为600℃、石墨化温度为850℃且催化剂为浓度为7.0 mmol g的乙酰丙酮铁时，所得石墨化碳具有较好的石墨化程度、微观层状结构且缺陷较小。玉米秸秆基石墨化碳产率达到22.20%。
