Selective CO2-to-C2H6 photoconversion over electron-rich Au anchored on In2O3 nanosheets

Abstract

Electron-rich Au anchored on In₂O₃ nanosheets inverts the C–C coupling thermodynamics from 0.82 eV to −1.42 eV, thereby promoting the formation of the key intermediate (*OCCO) in the photoreduction of CO₂ to C₂H₆, enabling the selective production of C₂H₆ with 85.1% electron selectivity and a 46.3 µmol g⁻¹ h⁻¹ evolution rate.
