摘要：

以硫酸钛、 四氯化锡和尿素为原料, 采用低温水热法一步合成了TiO2-SnO2复合氧化物. 采用X射线衍射(XRD), 扫描电子显微镜/能量色散X射线谱仪(SEM/EDAX)及紫外-可见光谱(UV-Vis)对产物的结构与性能进行表征分析, 考察了反应条件对产物晶体结构和形貌的影响. 结果表明, 在静止反应条件下Ti4+/Sn4+摩尔比为6~8时, 可以获得尺寸均一的金红石结构TiO2-SnO2复合氧化物微球, 其平均粒径为2 μm. 产物的紫外吸收性能优于同种方法制备的纯TiO2, SnO2及商品P25.

Abstract:

Using Ti(SO4)2, SnCl4 and urea as raw materials, TiO2-SnO2 composite oxide powders with sphe-rical morphology were synthesized by one-step low temperature hydrothermal method in aqueous solutions. The influences of reaction conditions on the structure of the products were investigated. The obtained samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), energy dispersive X-ray analysis(EDAX) and UV-Vis spectrometry. The results reveal that uniformly dispersed composite oxides with rutile structure are obtained with average diameters of 2 μm when the Ti4+/Sn4+ molar ratio is in the range of 6-8 without stirring, the UV absorption of the product is stronger than that of anatase TiO2, SnO2 and commodity P25.
