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.

Abstract: γ-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.
