Photocatalytic Characteristic of Fe-doped Tio2 with Phenol

Fe doped TiO2 particles were synthesized by sol-gel method. This gel was dried at 70 degrees C during 2 hours and afterwards was calcined at 450 degrees C during 4 h. Under calcinations at 450 degrees C (4 h), catalyst particle with an average diameter around 59 nm and monophasic anatase structure were obtained. The 0.3wt% Fe/TiO2 catalyst behaved as efficient and stable catalyst for the photodegradation of phenol solution. At the experimental conditions of initial phenol solution at 10 mg/L, initial pH of the phenol solution at 6.0, UV lamp at 20 W, catalysts concentration at 0.5 g/L, the COD removal of 99 % could be achieved after 240 min of photodegradation reaction.
