Preparation of the 2,4-dichlorophenol solution of Ce-doped Tio2 and its photocatalytic activity

Ce doped TiO2 catalyst was synthesized by sol-gel method. This gel was dried at 70 degrees C during 2 hours and afterwards was calcined at 500 degrees C for 4 h. Then, the anatase TiO2 catalyst power were obtained. The 0.3wt% Ce/TiO2 catalyst is efficient and stable catalyst for the photodegradation on the 2,4-DCP solution. At the experimental conditions of initial 2,4-DCP solution at 10 mg/L, UV lamp at 20 W, catalysts concentration at 0.5 g/L, the mineralization ratio at 98.14% could be achieved after 600 min of photodegradation reaction. And the Ce/TiO2 catalyst also showed photodegradation ability on 2,4-DCP unber simulate solar light, the mineralization ratio at 55.23% could be achieved after 600 min of solar photodegradation reaction.
