Li–N doped and codoped TiO2 thin films deposited by dip-coating: Characterization and photocatalytic activity under halogen lamp

•Li and N have a synergetic effect on photocatalytic efficiency of codoped TiO2 under halogen lamp.•(Li, N) dopants decrease the recombination rate of photogenerated e–h.•(Li, N) dopants induce an increase of the energy gap, Eg.•A decrease of crystallinity of the thin films seems to occur for high l...
