Preparation and properties of visible light responsive Y3+ doped Bi5Nb3O15 photocatalysts for Ornidazole decomposition

► A novel Y3+-Bi5Nb3O15 material was prepared. ► Y3+-Bi5Nb3O15 is firstly used for the photocatalytic degradation of Ornidazole. ► Possible pathway of Ornidazole degradation in aqueous solution is proposed.
