在反胶束体系中制备了硫化镉纳米粒子，通过在胶束溶液中加入硫醇修饰的硅酸铝粒子(ASSH)和温和搅拌的简单操作将其固定在ASSH上。将得到的纳米硫化镉-铝硅酸盐复合材料(ASCdS)作为光催化剂用于异丙醇水溶液中制取H_2。研究发现，硅酸铝的化学性质，如对水和其他反应物的亲和力，都会影响固定化硫化镉纳米颗粒的光催化性能。沸石颗粒对水和异丙醇具有亲和力，对H_2的生成具有良好的ASCdS光催化性能。
CdS nanoparticles, prepared in reverse micellar system, were immobilized onto thiol-modified aluminosilicate particles (ASSH) by a simple operation: addition of ASSH in the micellar solution and mild stirring. The resulting CdS nanoparticles–aluminosilicate composites (ASCdS) were used as photocatalysts for H2generation from 2-propanol aqueous solution. The chemical properties of the aluminosilicate, such as affinity for water and other reactants, were found to affect the photocatalytic property of the CdS nanoparticles immobilized. Zeolite particles, having affinity for water and 2-propanol, gave a good ASCdS photocatalyst with respect to H2generation.
