Wei, L. (author), Haije, W.G. (author), Grénman, Henrik (author), de Jong, W. (author)Hydrogen produced by the electrolysis of water using sustainable electricity will play an increasingly important role as an energy and a feedstock vector. Shifting from fossil to renewable resources means that new industrial platforms have to be set up to provide carbon-based fuels and bulk base chemicals to replace the current fossil...book chapter 2022

Wei, L. (author), Haije, W.G. (author), Kumar, Narendra (author), Peltonen, Janne (author), Peurla, Markus (author), Grenman, L.O.H. (author), de Jong, W. (author)Zeolite 13X and 5A supported Ni catalysts were synthesized for CO<sub>2</sub> methanation using the evaporation impregnation method. The influence of using different Ni precursors (nitrate, citrate, and acetate) as well as calcination temperatures on the catalyst properties and performance were investigated. XRD, SEM-EDX, TEM, STEM-EDX, N<sub...journal article 2020

Wei, L. (author), Azad, Hamza (author), Haije, W.G. (author), Grenman, L.O.H. (author), de Jong, W. (author)Methanation is a potential large-scale option for CO<sub>2</sub> utilization, and it is one of the solutions for decreasing carbon emission and production of synthetic green fuels. However, the CO<sub>2</sub> conversion is limited by thermodynamics in conventional reaction conditions. However, around 100 % conversion can be obtained using...journal article 2021

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

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
