Abstract

The TiO2-Fe3O4 supported bentonite has been synthesized. The syntheses of the TiO2-Fe3O4 based photocatalyst have been carried out by sol-gel method. The bentonite used for porous support was obtained from Pacitan, Indonesia. The mol ratio of Ti and Fe in this experiment was 1:1. The syntheses of the photocatalyst material were followed by calcinations. This experiment was focused on the effect of temperature calcinations toward Ti and Fe crystal phase, which was affected to the capability of the materials in photocatalysis of phenol degradation. The variation of the calcinations temperature was 500, 600 and 700oC. The physicochemical properties of TiO2-Fe3O4 bentonite samples were characterized by X-ray diffraction. Photocatalytic activity of the materials was evaluated by phenol photodegradation using UV light. The calcinations temperature was significantly influenced in the forming of anatase phase of TiO2 which was affected in the catalytic activity
