Abstract
Phenol is a toxic organic pollutants and difficult to treat. Using TiOSO4 as titanium source, urea as the precipitator,and zeolite as the carrier,we had prepared the nano-TiO2/zeolite material by homogeneous precipitation method. The effect of TiO2 loading amount,calcination temperature and the reusabiity on photocatalytic degradation of phenol were investigated by taking phenol as the degradation target. The results showed that the nano-TiO2/zeolite material with 30% TiO2 loaded,and calcined at 650℃ exhibited the best photocatalytic performance. The degradation efficiency of nano-TiO2/zeolite material towards phenol (20mg/L) was 91.6% when irradiated for 3.5h under 300W high pressure mercury lamp and the catalyst after five cycles still demonstrated excellent photocatalytic performance of 85 % of the photocatalytic degradation rate of phenol.关键词
