Sol-Gel Synthesis of Mesoporous TiO_2 Films for Visible Light Sensitive TiO_2/CdS Heterostructures

摘要

Mesoporous TiO_2 films were prepared by template assisted sol-gel method and used as support for deposition of CdS particles on its surface to produce visible light sensitive nanocomposites. The influence of the surface morphology of mesoporous titania matrix onto the TiO_2/CdS heterostructure formation was investigated using UV-Vis, IR, low-angle XRD, SEM and AFM methods.
