Preparation and characterization of mesoporous VOx–TiO2 complex oxides for …

Abstract. Mesoporous VOx–TiO2 with high surface areas were prepared using the procedure of evaporationinduced self-assembly combined with ammonia posttreatment. The samples were characterized by Xray diffraction (XRD), laser Raman spectroscopy (LRS), transmission electron microscopy (TEM), N2 adsorption, temperature-programmed reduction (H2-TPR), microcalorimetry for the adsorption of NH3, …
