Wei, L. (author), Kumar, Narendra (author), Haije, W.G. (author), Peltonen, Janne (author), Peurla, Markus (author), Grenman, L.O.H. (author), de Jong, W. (author)Zeolites 13X and 5A were modified with nickel and/or ruthenium for CO<sub>2</sub> methanation. The catalysts were prepared by evaporation impregnation and XRD, SEM-EDX, TEM, STEM-EDX, nitrogen physisorption, H<sub>2</sub>-TPR and NH<sub>3</sub>-TPD were used to characterize the physico-chemical properties of the catalysts. The physico...journal article 2020

Wei, L. (author), Grénman, Henrik (author), Haije, W.G. (author), Kumar, Narendra (author), Aho, Atte (author), Eränen, Kari (author), Wei, L. (author), de Jong, W. (author)Sub-nanometer zeolite 13X-supported Ni-ceria catalysts were synthesized for CO<sub>2</sub> methanation. XRD and SEM results show the structure and morphology of 13X zeolite after impregnation and calcination. Ce loading affected the catalysts’ metal dispersion, reducibility, basicity and acidity, and thence their activity and selectivity....journal article 2021
