Degradation of Phenol by Fe~(3+) Doped nano-TiO_2 Photocatalyst

摘要

Degradation properties of phenol using nano-TiO_2 as photocatalyst in aqueous solution were investigated. The effect of annealing temperature and ionic modification on the degradation was studied. The results showed that, 500°C annealed TiO_2 was better than 700°C annealed. Photocatalyst nano-TiO_2 material doped with Fe~(3+) was prepared quickly by sol-gel process and was used as photocatalyst to degrade phenol solution of 100mg/L under UV irradiation for 3 hours. UV spectrophotometer testing was made and found that two peaks at 210 nm and 270 nm were significantly become low, indicating that the phenol has been degraded. The phenol degradation rate was 94.18%.
