Figure 7. Structure-property analysis, activity test and mechanism study for samples. (A) Light intensity-dependence of temperature for samples supported on CeO₂ different loadings of Cu and Ga. (B) Light intensity-dependence of CO production rate for samples with different loadings of Cu and Ga on CeO₂. (C) O 1s: XPS spectra of 10Cu/CeO₂. (D) O 1s: XPS spectra of 10Cu5Ga/CeO₂. (E) in situ DRIFTS spectra analysis over 10Cu/CeO₂ during photothermal RWGS reaction. (F) Over 10Cu5Ga/CeO₂. (G) Schematic of photothermal RWGS reaction mechanism for catalyst supported Cu and Ga.
