TiO2 and TiO2-Carbon Hybrid Photocatalysts for Diuron Removal from Water

TiO2 and TiO2-activated carbon (AC) photocatalysts have been prepared (by sol-gel synthesis), characterized, tested in the removal of diuron from water under simulated solar light. The preparation variables two series catalysts are: (i) heat-treatment temperature bare (350, 400, 450 500 °C) (ii) activated content (0.5, 1, 5, 10 wt.%) TiO2-AC samples heat-treated at 350 °C. was previously by hydrothermal carbonization saccharose has spherical shape. does not determine efficiency for photocatalytic degradation, but clearly influences adsorption capacity. capacity increases with it is result combined photodegradation. Thus, sample highest (10 wt.% nominal) leads to removal. proved be capable degrading adsorbed dark conditions, which allows their regeneration.
