Fig. 6. (a) The absorbance intensity of hydroxyls at 3600 cm–1 in DRIFTS of 2.5 wt% RhFeLi/TiO2 NRs and 2.5 wt% RhFeLi/TiO2 Com versus time after switching the CO2 + H2 + Ar (CO2 : H2 = 1 : 3) flow to pure CO2 flow at 250 °C. (b) The absorbance intensity of formate at 1595 cm–1 in DRIFTS of 2.5 wt% RhFeLi/TiO2 NRs and 2.5 wt% RhFeLi/TiO2 Com versus time after switching the CO2 + H2 + Ar (CO2 : H2 = 1 : 3) flow to pure CO2 flow at 250 °C.
