Preparation of the 2, 4-dichlorophenol solution of Ce-doped TiO_2 and its photocatalytic activity

摘要

Ce doped TiO_2 catalyst was synthesized by sol-gel method. This gel was dried at 70°C during 2 hours and afterwards was calcined at 500°C for 4 h. Then, the anatase TiO_2 catalyst power were obtained. The 0.3wt% Ce/TiO_2 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/TiO_2 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.
