| 摘 要： | 本文系统研究了水热法制备的铁掺杂纳米TiO2和氮掺杂纳米TiO2在可见光照射下对挥发性有机物(volatile organic compounds,VOCs)的降解能力和降解产物.铁掺杂纳米TiO2和氮掺杂TiO2对光的吸收边分别红移到540 nm和580 nm;在可见光下具有良好的催化活性,24 h内对挥发性有机物的降解率达20%—50%,降解后的最终产物可能主要为CO2.

| 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. |
