Abstract
The elaborate thermodynamic reaction pathways on Ga2O3-decorated and -defective surfaces during photothermal catalytic CO2 conversion with H2O have been established. The basic site generated by Ga2O3 decoration on an anatase TiO2 (101) surface enhances the selective adsorption of CO2, and also balances VO formation and CO2 reduction activity. Surface-defect VO promotes the reaction thermodynamics but tends to be consumed; Ga2O3 helps to keep VO active. Ga2O3 and VO together further decrease the energy barrier of the rate-determining step, thereby promoting C1 production. More information can be found in the Research Article by Y.-W. Zhang et al. (DOI: 10.1002/chem.202104490).
