Reaction mechanism for Bi2O3 nanosheets. a In situ DRIFTS spectra for the adsorption and activation of CO2 in the presence of CH3OH under Xe-lamp irradiation for OV-rich-Bi2O3 nanosheets. Inset at the lower left: the DRIFTS of generation of •CO2–; inset at the lower right: the DRIFTS of DMC. b In situ DRIFTS spectra for the catalysts with CO2 and CH3OH under Xe-lamp irradiation for 60 min. c Quasi in situ XPS spectra of OV-rich-Bi2O3 and OV-poor-Bi2O3 nanosheets under the atmosphere of CO2 (0.2 MPa) at 373 K
