Abstract
Porous ZnO/SnO2 compound film was prepared by sol-dipping template method. The morphology and characteristics of the film were analysed by SEM and X-ray diffraction (XRD). The results showed that precursor sol concentration played an important role in the formation of porous structure. The thickness of inorganic wall increases with increasing sol concentration. The suitable sol concentration, which has a satisfactory permeation and a good pore structure, is about 0·4M. X-ray diffraction pattern showed that ZnO and SnO2 were wurtzite and rutile structure respectively.
