| Abstract: | Macroporous CdS/SiO2 was prepared with a new approach in which at first CdS nanoparticles were deposited on polymer microbeads without surfactant, then core-shell composite was self-assembled with sedimentation-aggregation, and at last macroporous material was obtained by the removal of the template. The results show that the morphology of core-shell composite could be tailored by the polymer template and the concentration of the reactant, and the shell thickness could be altered by the temperature and the aging time. This new idea was an effective method to prepare other macroporous composite with large-scale. |
