Study on Photocatalytic Performance of Nb Doped Rutile TiO₂ Treated by Ultrasonic

Abstract:

The thermal decomposition behavior of precursor of Nb doped rutile TiO₂ were prepared by sol-gel method. With ultrasonic treatment of 100W and 30min were investigated in TG-DSC, XRD and DRS. It has been shown that ultrasonic treatment could be made use of the phase transition. The absorbing performance of Nb doped rutile TiO₂ treated by ultrasonic was better than that of without treatment while wavelength above 400nm. It has been shown that Nb doped TiO₂ powders(1.0%,850°C) treated by ultrasonic has been better photodegradation efficiency, and the degradation efficiency was 94.2% after 6h.
