The Effect of Calcination Temperature on the Surface Microstructure and Photocatalytic Activity of TiO2Thin Films Prepared by Liquid Phase Deposition

BaV2O6 photocatalyst was prepared by liquid-phase deposition method in paper and different calcination temperature effecting photocatalytic activity were investigated. X-ray diffraction (XRD) has been employed to characterize the as-synthesized materials. The photocatalytic activity was evaluated by degradation of Methy lorange(MO) under the UV-light.It was found that as-prepared BaV2O6 with molar ratio of V5+ to Ba3+ be 2:1, pH=7 and calcinated under 500°C for 4h exhibits higher activity than any other calcination temperature. The highest degragation rate was about 65% or so in 100min.

TiO2/α-Al2O3is prepared by liquid-phase deposition method from titanium ammonium fluoride. The morphography and crystal form of supported catalyst are analyzed by XRD and SEM. The results show that anatase is detected when the calcination temperature is 800°C, the interaction of TiO2and support inhibit TiO2transfer into anatase. The addition of polyvinyl alcohol makes the active component evenly distributed. It is found that when support for catalyst is honeycomb column α-Al2O3, loading amount is 4.0%, and calcination temperature is 800°C, the CODcr removal rate could reach 66%. Furthermore, no obvious evidence of deactivation and intensity for the catalyst could be seen after running for 100 hours.
