Simultaneous irradiation of ultraviolet light and ultrasound to titania photocatalysis has been studied recently, where the titania particles suspended in aqueous medium and 20〜200 kHz ultrasound are generally used. In this work, we employed fibrous titania prepared by a sol-gel coating on a metal fiber and high frequency ultrasound driven at 2.4 MHz. In the presence of titania fiber, the synergy index was found to be very high compared to the other process.
