Preparation and photocatalytic property of BaV_2O_6 photocatalyst by liquid-phase deposition method

摘要

BaV_2O_6 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 BaV_2O_6 with molar ratio of V~(5+) to Ba~(3+) 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.
