摘　　要：在离子液体[BMIM]Br的辅助下,通过简单的水热法成功合成片状的γ-Bi2MoO6纳米材料.利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)与紫外-可见漫反射光谱(DRS)等分析测试手段对所得产物进行表征.探讨了离子液体的作用机制.考察了片状γ-Bi2MoO6对结晶紫(CV)染料的光催化降解性质.结果显示:离子液体辅助合成的片状γ-Bi2MoO6材料具有优异的光降解性能.γ- Bismuth molybdate nameplates were synthesized via an ionic liquid assisted hydrothermal system. The structure and morphology of the as-synthesized samples were characterized by X-ray diffraction （XRD）, field emission scanning electron microscopy （SEM） , fourier transform infrared （FT-IR） spectrum and UV-Vis diffuse reflectance spectrum（DRS）. The effect of the ionic liquid [ BMIM ] Br on the formation of γ-Bi2MoO6 was discussed in detail. The photocatalytic activity of the as-synthesized samples was evaluated by monitoring the degradation of crystal violet （CV） solution. The result showed that γ-BiEMoO6 nanoplates revealed much higher photocatalyst activity.
