Characterization of TiO2/ACF Preparation in Caprolactam Tetrabutyl Ammonium Bromide Ionic Liquid

To explore environmentally benign method for preparing TiO2, composite photocatalysts TiO2 immobilized on activated carbon fibers (TiO2/ACF) were prepared in caprolactam tetrabutyl ammonium bromide ionic liquid (CPL-TBAB ILs). The TiO2/ACF composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that nanoTiO2 particles of mixed grain phase were well deposited on the activated carbon fiber surface.
