    • 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 ...

    • 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 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 ...

    • 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 ...
