摘　　要：以葡萄糖为碳源、四种不同的碳材料为基材,通过水热合成制备出富羟基的核/壳结构碳基催化促进剂。所得催化促进剂壳层表面富含大量羟基,其氧含量高达16%~18%。通过使用富羟基核/壳结构碳基催化促进剂,能明显提升了纤维素水解成糖的效率。结果表明,利用含以碳纳米管为基材的纳米级催化促进剂体系,纤维素转化率及葡萄糖产率最佳,达到约96%及77.7%。Glucose and four different carbon materials were used as carbon source and substrates,respectively,to prepare hydroxyl-rich core/shell structured carbon-based catalytic accelerators successfully by hydrothermal synthesis.There existed a large number of hydroxyls on the shell surface of the catalytic accelerator with an oxygen content as high as 16%~18%.By using hydroxyl-rich core/shell structured carbon-based catalytic accelerators,the efficiency of cellulose hydrolysis to sugar could be significantly improved.The results showed that by using the carbon nanotube-based nanoscale catalytic system,the best conversion of cellulose and the yield of glucose could reach approximately 96%and 77.7%,respectively.
