Flexible Yttrium Coordination Geometry Inhibits “Bare-Metal” Guest Interactions in the Metal-Organic Framework Y(btc) (2016)
Journal Article
Auckett, J., Ogilvie, S., Duyker, S., Southon, P., Kepert, C., & Peterson, V. (2016). Flexible Yttrium Coordination Geometry Inhibits “Bare-Metal” Guest Interactions in the Metal-Organic Framework Y(btc). Energies, 9(10), Article 836. https://doi.org/10.3390/en9100836

Y(btc) (btc = 1,3,5-benzenetricarboxylate) is a metal-organic framework that exhibits significant adsorption of industrially-relevant gases such as H2, CH4, and O2. Previous studies have noted a surprising lack of close interactions between the adsor...
