Microwave Assisted Preparation and Characterization of Ionic Liquid [Bmim]PF₆ and Synthesis and Characterization of Titanium Dioxide Using [Bmim]PF₆ as Medium

Abstract:

[Bmim]PF₆ ionic liquid was synthesized through two-step reaction in the unmodified microwave oven and ionic liquid synthesis conditions were optimized, the influence factors of microwave-assisted synthesis ionic liquid was discussed. Titanium dioxide photo-catalysts using [Bmim]PF₆ ionic liquid as medium were prepared. Result indicated that the nanoparticle titanium dioxide obtained in [Bmim]PF₆ by microwave radiation exhibited higher photocatalytic activity than that by traditional methods, with the degradation ratio of phenol of 99.23% within 16 h.
