采用电喷离子化技术结合溶胶-凝胶技术制备多孔二氧化钛微球,并利用扫描电镜、红外光谱和X射线衍射等对所得微球的形貌和结构进行了初步的表征。结果表明,该法制备的微球表面不平滑,平均直径范围为350—600nm左右,主要呈锐钛矿晶相。小角X射线衍射的结果表明微球中可能存在有序的孔结构。 Porous titania microspheres were prepared by electrospray ionization combined with sol-gel technique. The morphology and structure of the obtained microspheres were characterized by scanning electron microscopy, infrared spectroscopy and X-ray diffraction. The results show that the surface of the microspheres prepared by the method is not smooth, the average diameter of about 350-600nm, mainly anatase crystal phase. The results of small angle X-ray diffraction show that there may be ordered pore structure in the microspheres.
