摘要

•Multifunctional TiO2 was coated on floating fly ash cenospheres.•TiO2 was integrated with carbonaceous layer from chitosan and Fe-N co-doping.•Carbonized chitosan improved the adsorption of pollutant and photon absorption ability of TiO2.•Modified TiO2 exhibited superior photocatalytic activity and better recyclability.
