Abstract

Abstract: We report a facile template-free method to fabricate monodisperse mesoporous TiO2 spheres using microporous titanium glycolates(TG) as precursor. By solvothermal treatment, microporous TG can be directly converted into mesoporous TiO2 spheres via in-situ hydrolysis. The products were characterized by XRD, SEM, TEM, FTIR and nitrogen absorption. The results show that the products exhibit high crystallinity, uniform morphology and tunable pore size. These integrated features would make the as-obtained mesoporous TiO2 materials have attractive applications in areas of environmental purification, energy conversion and storage.
