Fig. 4: FTIR spectra of CO2 adsorption under photoirradiation.
From: Enhanced CO evolution for photocatalytic conversion of CO2 by H2O over Ca modified Ga2O3
Difference FTIR spectra of the adsorbed CO2 species on Ga2O3_Ca_1.1 under photoirradiation for different hours. ~2.0 Torr of CO2 was introduced into the instrument.
