英文摘要Ce0.5Zr0.5O2 and gamma-Al2O3 supported nickel catalysts were investigated for CO2 adsorption and methanation using in-situ FTIR spectroscopy. The reaction pathway on Ni/gamma-Al2O3 is similar to that on Ni/Ce0.5Zr0.5O2, only differing in reactive basic sites. CO2 adsorption on medium basic sites of Ni/Ce0.5Zr0.5O2 results in monodentate carbonates. CO2 adsorbed on strong basic sites of Ni/gamma-Al2O3 will not participate in the reaction. It was assumed that monodentate formate derived from monodentate carbonate on medium basic sites, could be hydrogenated more quickly than bidentate formate derived from hydrogen carbonate. Medium basic sites were proposed to enhance CO2 methanation activity. (C) 2013 Elsevier B.V. All rights reserved.
