    • A nano-silicate material with exceptional capacity for CO2 capture and storage at room temperature 

      Cavalcanti, Leide Passos; Kalantzopoulos, Georgios N.; Eckert, J.; Knudsen, Kenneth Dahl; Fossum, Jon Otto (Journal article; Peer reviewed, 2018)
      In order to mitigate climate change driven by the observed high levels of carbon dioxide (CO2) in the atmosphere, many micro and nano-porous materials are being investigated for CO2 selectivity, capture and storage (CCS) ...

    • CO2 Adsorption Enhanced by Tuning the Layer Charge in a Clay Mineral 

      Hunvik, Kristoffer William Bø; Loch, Patrick; Wallacher, Dirk; Kirch, Alexsandro; Cavalcanti, Leide Passos; Rieß, Martin; Daab, Matthias; Josvanger, Vegard; Grätz, Sven; Yokaichiya, Fabiano; Knudsen, Kenneth Dahl; Miranda, Caetano Rodrigues; Breu, Josef; Fossum, Jon Otto (Peer reviewed; Journal article, 2021)
      Due to the compact two-dimensional interlayer pore space and the high density of interlayer molecular adsorption sites, clay minerals are competitive adsorption materials for carbon dioxide capture. We demonstrate that ...

    • The Impact of Thermal History on Water Adsorption in a Synthetic Nanolayered Silicate with Intercalated Li+ or Na+ 

      Michels Brito Miranda, Leander Edward; Fonesca, C. L. S. da; Méheust, Y.; Altoé, M. A. S.; Santos, E. C. dos; Grassi, G.; Droppa Jr., R.; Knudsen, Kenneth Dahl; Cavalcanti, Leide Passos; Hunvik, Kristoffer William Bø; Fossum, Jon Otto; Silva, G.J. da; Bordallo, H. N. (Peer reviewed; Journal article, 2020)
      For applications benefitting from the swelling properties of nanolayered silicates (clay minerals), it is of paramount importance to understand the hysteresis in the clay–water interaction. In this context, the present ...

    • Intercalation of CO2 Selected by Type of Interlayer Cation in Dried Synthetic Hectorite 

      Hunvik, Kristoffer William Bø; Seljelid, Konstanse Kvalem; Wallacher, Dirk; Kirch, Alexsandro; Cavalcanti, Leide Passos; Loch, Patrick; Røren, Paul Monceyron; Michels-Brito, Paulo Henrique; Droppa-Jr, Roosevelt; Knudsen, Kenneth Dahl; Miranda, Caetano Rodrigues; Breu, Josef; Fossum, Jon Otto (Peer reviewed; Journal article, 2023)
      Clay minerals are abundant in caprock formations for anthropogenic storage sites for CO2, and they are potential capture materials for CO2 postcombustion sequestration. We investigate the response to CO2 exposure of dried ...
