Abstract: The degradation performance of volatile organic compounds(VOCs) under visible light irradiation by Fe-doped and nitrogen-doped nanocrystalline TiO2 powders prepared by hydrothermal method has been investigated systematically in this article.The absorption spectral edge of Fe-doped and N-doped nano-TiO2 powders have been red-shifted to nearly 540 nm and 580 nm,respectively.Experimental results show that the degradation ratio of VOCs was over 20% to 50% within 24 hours.CO2 was one of the final degradation products.

Key words: doped nano-TiO2, visible light, degradation ratio, volatile organic compounds
