Abstract Bismuth Titanite (Bi4Ti3O12) platelets with surface defects were successfully synthesized via a simple ball milling route. The additive Li with strong reducibility stripped off the surface atoms from the (Bi2O2)2+ slabs and even (Bi2Ti3O10)2- perovskite layers, leaving abundant surface defects. The defect-rich Bi4Ti3O12 platelets with a narrowed band gap achieved excellent degradability, capable of degrading Rhodamine B (RhB) completely within 25 minutes under visible light irradiation. The results of this study demonstrated the extraordinary photodegradation performance of micro-sized catalysts.
