Synthesis, characterization and degradation of Bisphenol A using Pr, N co-doped TiO2 with highly visible light activity

► Nitrogen atoms are locally incorporated into the crystal lattice of TiO2, resulting in the band gap narrowing and the response to visible light. ► The praseodymium doping inhibits the anatase-to-rutile phase transformation and retards the growth of crystallite. ► Pr, N-codoped TiO2 exhibits enhanced visible-light photocatalytic activity compared to undoped TiO2, commercial P25 and N-TiO2. ► The synergistic effects of praseodymium and nitrogen lead to high photo-degradation of Bisphenol A under visible light irradiation.
