摘　　要：以XRD为主要表征手段,以三嵌段共聚物P123为模板剂,采用一步法制备介孔炭,研究了进料顺序、蔗糖添加量、晶化温度及氧化交联剂对介孔炭长程有序度的影响。结果表明,当P123与蔗糖的质量比m(P123):m(蔗糖)=1:1.25、晶化温度为100℃、硫酸为氧化交联剂时,介孔炭的长程有序度较好,BET和TEM测试表明,介孔炭的比表面积、孔径等数据具备介孔材料的典型特征。With XRD as the main means of characterization,using one-step preparation of mesoporous carbon,the influence of feed sequence,sucrose content,crystallization temperature and oxidative crosslinking agents on the degree long-range order of the mesoporous carbon were investigated. Results showed that when the mass ratio of P123：sucrose was 1：1. 25,crystallization temperature was 100 ℃,and sulfuric acid as the oxidation crosslinking agent,the long-range order of mesoporous carbon was better. BET and TEM showed that surface area and pore size were confirmed the typical characteristics of the mesoporous materials.
