Key Points

The research aims to evaluate how electron-rich gold (Au) on In2O3 nanosheets affects CO2 photoconversion efficiency by altering thermodynamics.
Utilization of electron-rich Au anchored on In2O3 nanosheets as a catalyst.
Analysis of C-C coupling thermodynamics pre- and post-catalyst application.
Formation of key intermediates, specifically OCCO, investigated under photoconversion conditions.
The thermodynamic barrier for C-C coupling decreased from 0.82 eV to -1.42 eV with the catalyst.
Formation of the key intermediate (OCCO) was promoted by the manipulated thermodynamics.
Enhanced selectivity for ethane (C2H6) production from CO2 was observed.

Abstract

Electron-rich Au anchored on In2O3 nanosheets inverse the C-C coupling thermodynamics from 0.82 eV to −1.42 eV, thereby promoting the formation of the key intermediate (*OCCO) and enabling selective CO2...
