Abstract : A new photocatalyst titania:activated carbon (TiO2:AC) composite was prepared by impregnating anatase type TiO2 nanoparticulates onto the activated carbon surface through a mild hydrothermal route. A varied ratio of TiO2 to {AC} was considered for impregnation. As-prepared TiO2:AC composite was characterized by various techniques such as powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), {BET} surface area and positron annihilation lifetime spectroscopy (PALS). Powder {XRD} results showed the persisting nature of anatase phase of TiO2 deposited on the activated carbon surface. The BET, {FTIR} and {PALS} results revealed the impregnation threshold. The TiO2 particulates were well adhered and uniformly dispersed on the carbon surface as confirmed by SEM.
