摘    要:利用γ-巯丙基三甲氧基硅烷及表面预吸附水解技术在MCM-41介孔分子筛孔道内部以化学键合的形式依次引入了CdS和TiO2纳米粒子.紫外-可见吸收光谱结果表明,借助于巯基的络合能力,MCM-41能有效地从反胶束中萃取CdS纳米粒子.利用小角XRD谱图成功地跟踪观察到了MCM-41介孔分子筛随纳米粒子的引入而产生的孔径变化.

关 键 词:CdS   TiO2   MCM-41   复合纳米材料

Abstract:thiopropyl tri methyl silicane and surface pre adsorption hydrolysis technique were used to accommodate CdS and TiO2 nanoparticles into the tunnels of MCM 41 meso porous sieves.UV Vis spectra showed that MCM 41 extracted CdS nanoparticles effectively from the reverse micelles by the chelation of thiol groups.The changes of meso tunnel diameter of MCM 41 were also observed with the introducing of nanoparticles in the low angle XRD patterns.
Keywords:CdS   TiO2   MCM 41   Nano composite
