中文摘要：

采用溶胶-凝胶法制备了TiO2-C纳米复合材料，利用XRD、SEM和TEM等方法对样品进行分析表征。实验结果表明：网络诱导剂的加入有利于样品在室温下静置后更快凝胶，经600℃焙烧3h后样品中二氧化钛晶粒有不同程度长大，其特征峰更加明显，且其中二氧化钛晶粒为锐钛矿型；乙酰乙酸乙酯的加入有利于溶胶-凝胶的形成，且随着乙酰乙酸乙酯加入量的增加，TiO2-C纳米复合材料的孔容和孔径均增加。

英文摘要：

Ti02-C nanoeomposite materials were prepared by using sol-gel process, which were characterized by XRD, SEM and TEM. Results showed that the precursors of TiO2 and carbon could be co-gelated soon at room temperature by adding propylene oxide as gelation initiator. Ti02 grain grows up after it is heated at 600 ℃ for 3 h, and its characteristic peak is more clear. The crystal structure of TiO2 is anatase. Ethyl acetoacetate as a complexing agent is beneficial for the formation of the gels. The pore volume and the pore diameter in the TiO2-C nanocomposite materials increase with the increasing amount of the ethyl acetoacetate.
