The V4+ doped in TiO2 lattice enhanced the visible light absorption of TiO2 while the V2O5 on the surface of TiO2 and W6+ in TiO2 lattice could trap photogenerated electrons and transfer them to CO2 and water adsorbed on the surface of catalyst, resulting in effective separation of photogenerated charges. CO2 photocatalytic reduction over V and W codoped TiO2 catalyst was conducted in an internal-illuminated honeycomb photoreactor under simulated sunlight irradiation. Due to the strong visible light absorption and effective separation of photogenerated charges caused by V and W codoping and stable chemical states of V and W during photocatalytic reaction, the V and W codoped TiO2 catalysts exhibited stable and enhanced photocatalytic activity comparing with pristine TiO2 and single metal doped TiO2. ? 2017 Elsevier B.V.CO2 photocatalytic reductionCodopingPhotoreactorSimulated sunlightTiO2[SDGs]SDG13journal article10.1016/j.apcatb.2017.07.0782-s2.0-85026680459https://www.scopus.com/inward/record.uri?eid=2-s2.0-85026680459&doi=10.1016%2fj.apcatb.2017.07.078&partnerID=40&md5=0d6f52b92d160aadbef4b63ff49717cc
