Preparation of TiO2 Films on Quartz Glass Plate and Its Study of Photocatalytic Properties in Ultrasound
TiO2 thin films were prepared successfully by dip-coating technique and sol-gel method on quartz glass plate. The photocatalytic properties of the fabricated TiO2 thin films to decompose the Methyl orange(MO) solution with or wihtout ultrasonic vibrations were investigated. Experimental results showed that TiO2 thin films had best photocatalytic properties when it was coated four layers and calcined at 500°C. The sonophotocatalytic technology is more effective for the decomposition of methyl orange than single TiO2 photocatalytic,the degradation rate increased by 35%.In addition,the degradation rate is affected by reaction time, the impact of ultrasonic power.
