a: Ni content and Ag content determined by ICP; b: Specific surface area calculated by BET method; c: Pore volume and pore size calculated by BJH method; d: Average size of metal particles determined by TEM; e: CO adsorption amount was determined by CO-chem; f: H2 consumption of Ag was determined by the difference between the H2 consumption for H2-TPR test after the oxidation by N2O and the CO adsorption amount for CO-Chem. |
