采用熔盐法合成纯的单斜晶系的Bi2WO6,利用XRD、SEM、DRS等对其进行表征,通过光催化降解甲基橙(MO)对其可见光催化性能进行表征,并与传统固相反应法制得的粉末样品做对比。结果表明:熔盐的使用可以使原来固相反应法的所需温度(900℃)降低到350℃。稳定性实验表明样品具有较好的循环使用稳定性。
The pure monoclinic Bi2WO6 was synthesized by molten salt method and its photocatalytic performance was characterized by XRD, SEM and DRS. The photocatalytic degradation of methyl orange (MO) Legal system of powder samples for comparison. The results show that the use of molten salt can make the original solid phase reaction temperature (900 ℃) to 350 ℃. Stability experiments show that the sample has good stability of recycling.
