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

To explore environmentally benign method for preparing TiO
₂
, composite photo catalysts TiO
₂
immobilized on activated carbon fibers (TiO
₂
/ACF) were prepared in caprolactam tetra butyl ammonium bromide ionic liquid (CPL-TBAB ILs). The TiO
₂
/ACF composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effects of different preparation condition were discussed by degradation of methyl orange (MO). The results showed that nano-TiO
₂
particles of mixed grain phase were well deposited on the activated carbon fiber surface. 96% of MO was removed under optimal preparation conditions.
