| Abstract: |
| Using F-N-TiO2 as photocatalyst and LED as the light source, the effects of ambient temperature, relative humidity and light intensity on the degradation of formaldehyde have been investigated. The results show that the ambient conductions have considerable influence on the degradation of formaldehyde by F-N-TiO2 under visible light irradiation. The optima ambient conditions for temperature and relative humidity are 40 ℃ and 50% respectively. The increase of LED light intensity is beneficial to the activity of photocatalytic degradation of formaldehyde. |
