Enhancement of the photocatalytic activity of TiO2 by doping onto Clinoptilolite towards degradation of Tetracycline abstract
The surface interaction between TiO2 (P25) and natural zeolite, Clinoptilolite, has been investigated by means of X-ray diffractometer (XRD), scanning electron microscopy (SEM) and surface area (BET) measurement. Photocatalytic degradation rate of tetracycline (TC), a model of recalcitrant pollution, in aqueous system has been measured to compare the photocatalytic activities of unmodified TiO2 and composite TiO2/CP under UV irradiation. The degradation extent was determined via UV–Vis absorption spectroscopy. A higher TC removal efficiency was attained with UV-TiO2-CP when compared with UV-TiO2. In addition, immobilization of TiO2 onto zeolite permitted easier separation of the adsorbent from the treated water. It was concluded that a TiO2/Clinoptilolite composite is a highly efficient and good photocatalyst/adsorbent hybrid material that can be utilized in the remediation of environmental pollution.
