In this research, the catalytic performance of the TiO 2 nanotubes prepared by electrochemical anodizing method was investigated in removal of DBT from a model oil through ODS process under thermal and optical conditions. The catalyst, SEM, XRD, Raman and UV-Visible analyzes were used to identify. The different parameters such as temperature, mole ratio of H 2 O 2 and volume ratio of fuel to extractive solvent were investigated. Under optimum conditions, the removal of DBT reached up to 98% and 96% for thermal and optical conditions respectively. The catalyst recycled 8 times without significant decrease of catalytic activity.
