Synthesis and Properties of Hollow Glass Spheres/ TiO2 Composite

doi:10.7517/j.issn.1674-0475.2012.06.447

Abstract

Abstract: Anatase TiO₂ shells deposited on hollow glass microspheres with tunable morphologies were successfully prepared through a controllable chemical precipitation method with urea as the precipitator, and thus glass/TiO₂ core/shell composite hollow microspheres were fabricated. The phase structure, morphology, particle size, shell thickness, and the chemical compositions, of the composite microspheres were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectrum and Raman spectra. The probable growth mechanism of the TiO₂ shells and the formation process of the core/shell composite microspheres were proposed.

Key words: hollow glass microspheres, TiO₂, core/shell, urea
