Synthesis of nanocomposite based on Semnan natural zeolite for photocatalytic degradation of tetracycline under visible light

摘要: This study investigated the photocatalytic behaviors for nanocomposite of TiO2 P25 and Semnan natural zeolite in decomposition tetracycline under visible light an aqueous solution. The structural features composite were by a series complementary techniques that included X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), surface area (BET) measurement, ultraviolet-visible diffuse reflectance (DRS). measurement disclosed enhancement ~2 times synthesized TiO2/Semnan than commercial P25. as-prepared photocatalyst (TiO2/Semnan zeolite) showed pH dependence more 87% could be degraded from solution irradiation within 90 min at 6. excellent catalytic ability was mainly attributed to hybrid effect adsorbent. results provided new insight into performance active photocatalysts on treatment pharmaceutical wastewater. In addition, immobilization onto permitted easier separation adsorbent treated water.
