Fig. 5: The investigation of potential reaction mechanism on Ce-CuZn catalyst.
From: A Ce-CuZn catalyst with abundant Cu/Zn-OV-Ce active sites for CO2 hydrogenation to methanol
a CO-DRIFTS results of CuZnCe after purged by He for 20 min at 30 °C. b The result of in-situ DRIFTS for CO2 hydrogenation at 260 °C. c Transient in-situ DRIFTS experiments on Ce-CuZn sample, and the peak intensity of HCOO* species at 1585 cm−1 as a function of time when the reaction atmospheres were switched from CO2 to H2, CO2 + H2, and Ar.
