Fabrication of composite coating spheres with silica sphere/titania shell structure by heterogeneous nucleation-and-growth processing

Fabrication of composite coating spheres with silica sphere/titania shell structure by... Monodispersed titania spheres have an important application in photocatalysts, but it is difficult to fabricate monodispersed titania spheres. In order to solve this problem, a novel and general processing (heterogeneous nucleation-and-growth processing) was used to prepare monodispersed composite coating spheres. Composite coating spheres with silica spheres/titania shell structures were fabricated by heterogeneous nucleation-and-growth processing. Effects of titania content in composite coating particles versus concentration of tetrabutyl titanate, pH value, reaction time and reaction temperature were studied. A homogeneous titania layer on silica spheres was confirmed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive X-ray spectra (EDX). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
