Abstract

To fabricate an efficient catalyst for low-temperature CO2 methanation with industrial development prospects, herein, we employed Ce-UiO-66 derived CeO2 (CeO2-U), instead of CeO2 prepared through traditional precipitation and cerium nitrate calcination to prepare the Ru catalysts for CO2 methanation. Compared with the Rh catalysts supported on CeO2 prepared by conventional methods, the CeO2-U-supported Ru catalyst (Ru/CeO2-U) boosted an excellent catalytic performance for CO2 methanation, giving a high CO2 conversion of 82 % at 300 °C with ∼100 % methane (CH4) selectivity. Characterization results revealed that the CeO2-U material with abundant pores and small grains was formed by the pyrolysis of Ce-UiO-66, which promoted the interaction between Ru and CeO2-U, resulting in a high concentration of oxygen vacancies and enhanced CO2 and H2 adsorption capacity of the Ru/CeO2-U catalyst. In situ diffuse reflectance infrared Fourier transform experiments illuminated that Ru/CeO2-U follows the co-existence path of formate and CO intermediates during methanation. CO∗ and HCOO∗ intermediates can be hydrogenated to form CH4, and a small amount of adsorbed CO would desorb to form the CO gas at high temperatures.
