Sol Gel Process

nano-sized TiO2 doped with different percentage of N was prepared quickly by sol-gel process，and the photocatalytic properties of degradation dyes wastewaters were studied under stimulant solar light irradiation in the ambient air. Some properties of photocatalysts were characterized by the means of XPS, UV-Vis ,XRD, and degradation loss. The results showed the catalytic activity was the best when the doped of nitrogen was 0.5% at calcinated 400°C，and the degradation of the methylene blue was almost completed.

Solar Light Irradiation

Nickel oxide (NiO) thin films were successfully deposited by sol-gel dip-coating method on glass substrates. The structural, morphological and optical properties in addition to the photocatalytic activity of the prepared films were investigated. The results show that the films have a polycrystalline NiO cubic structure with dense NiO grains and average optical transmittance in the visible region. The photocatalytic properties of the films were studied through the degradation of methylene blue and 89% of degradation was achieved for 4.5h of solar light irradiation exposure which indicates the capability of NiO photocatalytic activity.
