Effect of Ionic Liquid on the Morphology of TiO2 Nanoparticles
Abstract: This article focused on the preparation and photocatalytic properties of titanium dioxide prepared by hydrothermal synthesis of titanium dioxide, hydrochloric acid and titanium tetrachloride by ionic liquid and N-ethyl-pyridine tetrafluoroborate ([EPy] BF4) synthesis of TiO2 powder. The nanometer particles TiO2 could be analyzed and characterized by XRD spectra and SEM.The photocatalytic activity of TiO2 could be studied through the degradation of methyl orange. Experimental studies have shown that the higher the surface area, the more active groups, the higher the photocatalytic activity for the adsorption of methyl orange the more obvious.
