Preparation of Nanosized TiO2 Particles via Ultrasonic Irradiation and Their Photocatalytic Activity on the Decomposition of 4-Nitrophenol
Oh CW, Lee GD, Park SS, Ju CS, Hong SS
TiO2 nanoparticles were prepared by hydrolysis of TTIP (titanium tetraisopropoxide) using an ultrasonication technique coupled with a sol-gel method. The physical properties of nanosized TiO2 were investigated. The photocatalytic degradation of 4-nitrophenol was studied by using a batch reactor in the presence of UV light. The crystallite size of the anatase phase is increased with an increase of REtOH ratio (EtOH/H2O molar ratio). The particles’ crystallite size prepared with and without ultrasonic irradiation is marginally different. Those particles prepared with ultrasonic irradiation show a higher activity on the photocatalytic decomposition of 4-nitrophenol compared to those prepared without ultrasonic irradiation. The photocatalytic activity decreases with an increase of REtOH ratio. In addition, the photocatalytic activity shows the highest value on the titania particle calcined at 500 ℃.
