中文摘要：

采用一步法制备出有序介孔炭原位负载纳米硫化镉（CdS）粒子复合材料。该法以酚醛树脂、硫脲、硝酸镉为前驱体，三嵌段共聚物F127为模板剂，最终炭化得到有序介孔炭／CDS纳米复合材料，并采用XRD、BET和TEM等技术对产物进行表征。该复合材料具有有序的孔道结构，均一的孔直径（3．4～4．1nm）和大的比表面积（554．2m^2／g）。纳米CdS粒子为较稳定的六方晶相，粒径均一，且高度分散在有序介孔炭内，随着CdS粒子含量的增加，介孔炭有序度降低。

英文摘要：

Ordered mesoporous carbon/CdS composites have been synthesized by a ＂one-pot＂ assembly strategy associated with a direct carbonization process using phenolic resol as the carbon source, thiocarbamide and cadmium nitrate as matrix precursor and amphiphilictri block copolymer Pluronic F127 as a template. The composite structure was characterized by XRD, BET and TEM. The obtained mesoporous CdS/carbon composites with ordered mesostructures have uniform pore sizes （3.5-4.1 nm） and high spe- cific surface areas （554.2 m^2/g）. The CdS nanoparticles were dispersed evenly on the mesoporous carbon surface. The mesostruc- ture ordering decreases with the increase of CdS content.
