Sun, Chao; Summa, Paulina; Wang, Ye; Swirk Da Costa, Katarzyna; Miro i Rovira, Albert; Swierczek, Konrad; Hu, Changwei; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2022) -
Co-precipitated ni-mg-al hydrotalcite-derived catalyst promoted with vanadium for co<inf>2</inf> methanation
Summa, Paulina; Swirk, Katarzyna; Wierzbicki, Dominik; Motak, Monika; Alxneit, Ivo; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2021)Co-precipitated Ni-Mg-Al hydrotalcite-derived catalyst promoted with vanadium were synthesized with different V loadings (0–4 wt%) and studied in CO2 methanation. The promotion with V significantly changes textural properties ... -
Effect of cobalt promotion on hydrotalcite-derived nickel catalyst for CO2 methanation
Summa, Paulina; Swirk, Katarzyna; Wang, Ye; Samojeden, Bogdan; Rønning, Magnus; Hu, Changwei; Motak, Monika; Da Costa, Patrick (Peer reviewed; Journal article, 2021)A series of cobalt-promoted Ni-Mg-Al hydrotalcite-derived catalysts were tested towards CO2 methanation reaction. The best among examined catalysts was the one with 1 wt% of cobalt in fresh hydrotalcite, obtaining 77% of ... -
Excess-Methane CO2 Reforming over Reduced KIT-6-Ni-Y Mesoporous Silicas Monitored by In Situ XAS–XRD
Świrk Da Costa, Katarzyna; Summa, Paulina; Gopakumar, Jithin; van Valen, Youri; Da Costa, Patrick; Rønning, Magnus (Journal article; Peer reviewed, 2023)Making Europe less dependent on imported fuels requires a long-term strategy. Low-quality natural gas and biogas could be used to mitigate the energy crisis, and excess-methane dry reforming has the potential to upgrade a ... -
Optimization of Co-Ni-Mg-Al mixed-oxides CO2 methanation catalysts with solution combustion synthesis: On the importance of Co incorporation and basicity
Summa, Paulina; Swirk, Katarzyna; Gopakumar, Jithin; Samojeden, Bogdan; Motak, Monika; Rønning, Magnus; Van Beek, Wouter; Da Costa, Patrick (Peer reviewed; Journal article, 2023)Hydrogenation of CO2 to methane is a promising prospect for the utilization of carbon dioxide. Ni-Mg-Al mixed oxides have been reported as a catalyst for this process. Their promotion with cobalt allows to improve Ni ...
