摘要：Titania pillared montmorillonite from Indonesian montmorillonite by using titanium isopropoxide as precursor was successfully prepared. Physico-chemical character of material by using x-ray diffraction, gas sorption analyzer, diffuse reflectance UV-Visible, scanning electron microscope (SEM) and energy dispersive x-ray (EDAX) showed the dipersion of titania in dominantly anatase phase that is theoretically active as photocatalyst. The photoactivity was evaluated in methylene blue photodegradation and Eschericia coli inactivation. The kinetics of metylene blue photodegradation indicate the significant role of prepared material as photocatalyst as well as in E.coli inactivation. Photodegradation of methylene blue over prepared material shows the fitness to Langmuir-Hinshelwood model
