- The bentonite suspension was prepared and used as porous support for synthesis of TiO2-Fe3O4 based photocatalyst with varying TiO2 loading. The variations TiO2-Fe3O4 of in this experiment were 1:1 and 2:1. the synthesis of the photocatalytic materials have been carried out by sol-gel method and followed by calcination. The temperatures of calciantion were varried at 500, 600 and 700oC. The physicochemical properties of TiO2-Fe3O4 bentonite samples were characterised by X-ray diffraction. Photocatalytic activity of the materials was evaluated by phenol photodegradation using 20W UV light for 60 minutes. The titania content in the materials significantly influenced the physicochemical properties and catalytic activity.
