摘　　要：以淀粉为碳源,硫酸作为催化剂,借助水热碳化的方法制备出了淀粉基碳材料。研究了硫酸的浓度、碳化温度及碳化时间对淀粉基胶体碳收率的影响。并通过红外光谱、热重分析及扫描电镜等手段对淀粉基碳的化学特性进行了表征。A starch carbon was prepared using starch as carbon source and sulfuric acid as catalyst using hydrother- mal carbonization method. The effects of sulfuric acid concentration,carbonization temperature and carbonization time on the yield of starch-based colloidal carbon were optimized. Finally,the chemical properties of starch-based carbon were char- acterized by means of infrared spectroscopy,thermal analysis and scanning electron microscopy.
