Study on Degradation of Dyes Wastewater by N-Doped TiO₂

Abstract:

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.
