Degradation of methylene blue using pillared TiO 2 -WO 3 onto deoiled spent bleaching earth (DSBE) has been conducted. Pillarization with TiO 2 -WO 3 on DSBE using rarasaponin as surfactant. The structural and morphological of material has been carried out by X-ray fluorescence (XRF), and scanning electron microscopy coupled to the energy dispersive spectroscopy (SEM-EDX). Characterizations results show the increase composition of SiO 2 . The calcination result at 500°C show the TiO 2 -WO 3 was deposited on the DSBE surface and suspected there is existence of Ti and W metals on the DSBE layer. The catalytic performance of TiO 2 -WO 3 /DSBE for photodegradation of methylene blue under visible light was 99.85 % within 30 minutes.
