在有无表面活性剂CTAB辅助下,利用简单的水热法合成八面体和片状γ-Bi2MoO6.通过XRD、SEM、PL等对合成产物进行表征,由紫外可见漫反射(UV-vis)光谱发现产物在可见光域具有明显的光学吸收.以罗丹明B为目标降解产物,研究了γ-Bi2MoO6的光催化活性.结果显示:八面体γ-Bi2MoO6在太阳光下表现出高的光催化活性,罗丹明B的降解率达到95.7%,其主要归因于样品具有较低的光生电子-空穴的复合率.该方法为合成具有潜在光学应用的纳米多组分金属氧化物提供了一个温和、低廉的路线.
The octahedral and flaky γ-Bi2MoO6 were synthesized by simple hydrothermal method with or without surfactant CTAB.The synthesized products were characterized by XRD, SEM and PL, and characterized by UV-vis spectroscopy The results showed that the octahedral γ-Bi2MoO6 showed high photocatalytic activity in sunlight, and the photocatalytic activity of γ-Bi2MoO6 was also studied. The degradation rate of Rhodamine B was 95.7%, which was mainly attributed to the low recombination rate of photo-induced electron-hole in the sample.This method provided a mild, stable, and reproducible method for the synthesis of nanocomposite metal oxides with potential optical applications, Cheap route.
