The porous sol-gel silica thin films were prepared on silicon substrate by the dip coating process. The surface roughness and microstructure of the film was measured by optical microscopy and AFM .Coating thickness and refractive index were measured by ellipsometry method. Influence of withdrawal speed and concentration of colloid was investigated for the thickness of silica. The relation of the thickness and withdrawal speed was fitted by the linear and power functions, and the results were analyzed and compared. It was found that the films with the same thickness prepared by different concentrations of colloid have different refractive indexes. The experimental results indicated that the thickness and refractive index of the film can be controlled by changing the withdrawal speed and colloid concentration.

Porous TiO2 films were prepared through dip-coating on glass substrates using several different templates. Dip-coating process was optimized to prepare the three layered films. The film prepared with PEG1000 has the maximum activity compared with the other films using CTAB and HST. While PEG molecular weight is in the range from 400 to 6000, methyl orange degradation rate reaches its maximal value when using PEG1000. Two comparatively high activities can be found at the ratios of PEG1000:PEG400 as 3:1 and 1:2. The 1:2 ratio is the optimal one. PEG1000 seems to be more suitable of being used as a template to prepare porous TiO2 film with high photocatalytic activity. After 200 min of irradiation, 98.6 % of the initial dye can be degraded on the film prepared using 2 g of PEG1000.
