Synthesis of Continuous Mesoporous Ga-Doped Titania Films with Anatase Crystallized Framework
Abstract:Here we report synthesis of ordered mesoporous titania films with various amounts of Ga content. The influence of Ga contents on mesostructural ordering, surface morphology, thermal stability, and anatase crystallinity is carefully investigated, by using grazing incidence small angle X-ray scattering (GISAXS), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), and Raman spectroscopy. The presence of highly dispersed Ga contents in the titania frameworks can promote the thermal stability of mesoporous titania structures, resulting that the anatase crystallization successfully proceeds without collapse of mesostructures.
