摘要/Abstract

摘要： 以钛酸丁酯、硝酸铋及钨酸钠为前体，采用溶胶凝胶法及溶剂热法制备Bi₂WO₆-TiO₂复合光催化剂，运用X射线衍射（XRD）、紫外-可见光吸收光谱（UV-vis）、扫描电镜（SEM）、能谱分析（EDS）及光电流等方法表征复合材料的结构。考察了Bi₂WO₆-TiO₂复合光催化剂对Cu（Ⅰ）-EDTA络合水体复合污染的处理性能以及光反应后复合催化剂的新用途，并对其协同处理机制进行探讨。结果表明：相较于单一Cu（Ⅱ）及EDTA，该复合光催化剂在可见光下表现出对Cu（Ⅱ）-EDTA络合水体更高的处理效率。当Bi₂WO₆含量为5%时，复合光催化剂表现出最高的光催化活性。沉积过Cu及CuO的Bi₂WO₆-TiO₂光催化剂对有机污染物的光降解效率有着显著提升。

Abstract: The Bi₂WO₆-TiO₂ composite photocatalysts were prepared by sol-gel and solvent-thermal method with butyl titanate,bismuth nitrate and sodium tungstate as precursors. The structure of the samples was characterized by X-ray diffraction(XRD),ultraviolet-visible spectroscopy(UV-vis),scanning electron microscope(SEM),energy dispersive spectrometer(EDS)and photoelectrochemical measurements. The photocatalytic performance of Bi₂WO₆-TiO₂ on the treatment of Cu(Ⅱ)-EDTA combined pollutions in complexing water and the new application of used photocatalysts were investigated. Furthermore,the synergetic treatment mechanism for the combined pollutions was discussed. The results demonstrated that the composite photocatalyst exhibited higher treatment efficiency for Cu(Ⅱ)-EDTA combined pollutions than that for single Cu(Ⅱ) or EDTA under visible light irradiation. The composite showed the best photocatalytic activity when the Bi₂WO₆ content reached to 5%. The Bi₂WO₆-TiO₂ composite with Cu and CuO deposited remarkably improved the photocatalytic degradation of organic pollutions.
