Practical solar fuel production via two-step solar thermochemical CO2 splitting (STCS), a promising method. We demonstrate that FeNi alloy embedded in perovskite substrate enables near complete CO2 splitting and record CO production rate of 381 mL g-1 min-1 (STP). This unprecedented performance is ascribed to stabilization of oxidized Fe cations by in-situ involving into robust perovskite matrix. The thermodynamic analysis predicts a solar-to-fuel efficiency as high as 58% even without any sensitive heat recovery.
