    • Carbon-resistant NiO-Y2O3-nanostructured catalysts derived from double-layered hydroxides for dry reforming of methane 

      Swirk, Katarzyna; Zhang, Hailong; Li, Shanshan; Chen, Yaoqiang; Rønning, Magnus; Motak, Monika; Grzybek, Teresa; Da Costa, Patrick (Peer reviewed; Journal article, 2021)
      Yttrium promoted Ni/Mg/Al double-layered hydroxides were prepared through co-precipitation method and calcined at 550 °C for 5 h in order to obtain nanostructured mixed oxides. The catalysts were tested in dry reforming ...
    • Ce- and Y-Modified Double-Layered Hydroxides as Catalysts for Dry Reforming of Methane: On the Effect of Yttrium Promotion 

      Swirk, Katarzyna; Rønning, Magnus; Motak, Monika; Beaunier, Patricia; Da Costa, Patrick; Grzybek, Teresa (Journal article; Peer reviewed, 2019)
      Ce- and Y-promoted double-layered hydroxides were synthesized and tested in dry reforming of methane (CH4/CO2 = 1/1). The characterization of the catalysts was performed using X-ray fluorescence (XRF), X-ray diffraction ...
    • 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 ...
    • Dry reforming of methane over Zr- and Y-modified Ni/Mg/Al double-layered hydroxides 

      Swirk, Katarzyna; Galvez, Maria Elena; Motak, Monika; Grzybek, Teresa; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2018)
      Zr- and Y-promoted Ni/Mg/Al double-layered hydroxides were investigated in dry reforming of methane, DRM (10% CH4, CH4/CO2 = 1, GHSV = 20,000 h−1) for the first time. Modification of the double-layered hydroxides with 5 wt% ...
    • 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 ...
    • Effect of low loading of yttrium on Ni-based layered double hydroxides in CO2 reforming of CH4 

      Swirk, Katarzyna; Motak, Monika; Grzybek, Teresa; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2018)
      Ni/Al/Mg layered double hydroxides (LDHs) modified with low loading of yttrium (0.2 and 0.4 wt%) were used in dry reforming of methane at 700 °C. Physicochemical characterization, such as: X-ray fluorescence, N2 sorption, ...
    • Syngas production from dry methane reforming over yttrium-promoted nickel-KIT-6 catalysts 

      Swirk, Katarzyna; Galvez, Maria Elena; Motak, Monika; Grzybek, Teresa; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2018)
      Dry reforming of methane was studied over Ni,Y-promoted KIT-6 ordered mesoporous silicas, prepared by incipient impregnation (nickel content 12 wt%, yttrium content of 4 wt%, 8 wt% or 12 wt%). The catalysts were characterized ...
    • Unraveling catalytic properties by yttrium promotion on mesoporous SBA-16 supported nickel catalysts towards CO2 methanation 

      Sun, Chao; Swirk, Katarzyna; Wang, Ye; Li, Li; Fabbiani, Marco; Hulea, Vasile; Rønning, Magnus; Hu, Changwei; Da Costa, Patrick (Peer reviewed; Journal article, 2021)
      The ordered mesoporous silica SBA-16 with high specific surface area and pore volume was synthesized and used to prepare Ni/SBA-16 catalysts promoted with yttrium. These promoted catalysts were tested in CO2 methanation ...
    • Yttrium promoted Ni-based double-layered hydroxides for dry methane reforming 

      Swirk, Katarzyna; Galvez, Maria Elena; Motak, Monika; Grzybek, Teresa; Rønning, Magnus; Da Costa, Patrick (Journal article; Peer reviewed, 2018)
      Yttrium modified Ni-based double-layered hydroxides were tested as novel catalysts in dry methane reforming. The catalysts were characterized by XRF, BET analysis, XRD, TPR-H2, TPD-CO2, TGA/DSC-MS, H2 chemisorption and ...
