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(3.4~4.1 nm)和大的比表面积(554.2 m2/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。
Ordered mesoporous carbon/CdS composites have been synthesized by a“oneˉpot” 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. 5ˉ4. 1 nm) and high speˉ cific surface areas (554. 2 m2/g). The CdS nanoparticles were dispersed evenly on the mesoporous carbon surface. The mesostrucˉ ture ordering decreases with the increase of CdS content.
