To the best of our knowledge, photo-degradation of Reactive Black 5 dye（RB5） using ilmenite under solar irradiation is still lacking. In the present study, the physicochemical properties of ilmenite were characterized by using X-ray diffraction（XRD）, Scanning electron microscope（SEM）, BET and Raman Spectroscopy. Based on our results obtained, 73% solar-driven photo-degradation of RB 5 was successfully obtained when the catalyst loading increased up to 2.0 g/L for 20 min. In general,the photo-degradation of RB 5 by ilmenite followed first-order kinetics. The p H had a significant effect,with the most rapid degradation occurring at p H less than 7.展开更多
