摘要: Abstract Mesostructured ZrO 2 –TiO nanoparticles with different contents have been synthesized by an ionic liquid-assisted hydrothermal route. The prepared materials were characterized means of X-ray diffraction (XRD), nitrogen adsorption–desorption, transmission electron microscope (TEM), photoelectron spectroscopy (XPS), UV–vis diffuse reflectance spectra analysis (DRS) and NH 3 -TPD technique. obtained exhibit large specific surface area uniform pore sizes. Introduction species can effectively suppress phase transformation from anatase to rutile promote thermal stability materials. photocatalytic activity the sample is higher than that TiO commercially available Degussa P25. high be attributed stronger adsorption in ultraviolet region, area, smaller crystal size increased OH groups.
