Abstract Photo‐thermochemical cycle (PTC) is a promising method to converting CO 2 to solar fuels. To study the mechanism of CO 2 reduction based on PTC, sol‐gel synthesized titanium dioxide (ST) and Mn‐doped TiO 2 (MT) films were produced and applied to the PTC under simulated solar light irradiation. Commercial P25 (PT) was used as a reference. Experiments show that Mn‐doped TiO 2 produced more CO than undoped TiO 2 and P25. The average CO production of 1.0 wt% MT by the PTC was 32.19 μmol⋅m −2 ⋅h −1 ), 4.36 times than that of ST and 3.63 times that of PT. Various characterization methods were conducted to investigated the effect of Mn ions doping on the photoresponse and charge transfer of samples. Density functional theory (DFT) calculations were also performed to verify the analysis and enhance the PTC mechanism. In conclusion, several key factors that Mn ions promote CO 2 conversion have been clarified.
