Title: Facile synthesis of mesoporous core-shell TiO{sub 2} nanostructures from TiCl{sub 3}

Abstract

Highlights: {yields} Stable TiCl{sub 3} solution is adopted as Ti sources. {yields} Low-cost glucose assisted facile solvothermal reactions. {yields} Exquisite core-shell morphology and mesoporous structure of TiO{sub 2} nanostructures. {yields} Superior photocatalytic activity of TiO{sub 2} nanostructures in UV light irradiation. -- Abstract: The present study reports the synthesis and formation process of mesoporous core-shell TiO{sub 2} nanostructures by employing a glucose-assisted solvothermal process using water-ethanol mixture as solvent and subsequent calcination process at 550 {sup o}C for 4 h. X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy and nitrogen adsorption-desorption analysis were used to investigate the structural properties of these nanostructures. By optimizing the preparation conditions, especially the contents of water and ethanol in the mixture solvent, mesoporous core-shell TiO{sub 2} nanostructures were obtained. These mesoporous nanostructures have anatase phase and exhibit the superior photocatalytic activity. This synthesis route is facile due to the usage of stable and low-cost Ti precursor such as TiCl{sub 3} and is thus applicable for large-scale production.
