Design of Supported Nanoparticles in Ionic Liquid Medium and Its Photocatalytic Applications.

摘要

In this project, monometallic Ag nanoparticle doped titania was synthesized via nanoparticle encapsulation method using [BMIM]PF6ionic liquid. The material was thoroughly characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscope (SEM), Energy Dispersive X-ray (EDX) Spectroscopy and UV-Vis spectroscopy. Efficiency of the catalyst was evaluated on photodegradation of methylene blue (MB) dye under visible light irradiation. Results shows that Ag-doped titania in ionic liquid exhibited much better photodegradation (96%) as compared to Ag-doped titania in methanol medium (65%) in 210 min.
