| 摘 要： | 以聚乙烯吡咯烷酮(PVP)、钨酸铵(NH4)10W12O41]和柠檬酸铋铵(C6H13BiN2O7.H2O)为原料,利用静电纺丝技术成功制备了PVP/C6H13BiN2O7.H2O-(NH4)10W12O41(简写为PVP/BiWO)前躯体,对PVP/BiWO缓慢控温处理制得Bi2WO6。采用差热-热重分析(TG-DTA)、X射线粉末衍射(XRD)、傅里叶红外光谱(FTIR)、X-射线光电子能谱(XPS)、场发射扫描电镜(FE-SEM)、紫外可见漫反射(UV-Vis-NIR/DR)等分析手段研究热处理温度对材料结构的影响,通过罗丹明B(RhB)光降解反应研究其光催化性能。结果表明,可见光照射下,热处理温度600℃时材料的光催化活性最好,并探讨了其光催化机理。

| Abstract: | PVP/C6H13BiN2O7·H2O-(NH4)10W12O41 precursors have been successfully fabricated by electrospinning technique in the presence of polyvinyl pyrrolidone,and then the electrospun precursors were calcined at different temperatures.The samples were characterized by thermogravimetry-differential thermal analysis(TG-DTA),X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(FE-SEM) and UV-Vis-NIR diffuse reflectance(UV-Vis-NIR/DR),respectively.The visible-light photocatalytic activity of samples were evaluated with rhodamine B(RhB) as a probe.The results showed that Bi2WO6 was obtained at 600 ℃ and the best photocatalytic activity was achieved under visible light irradiation. |
