Some studies of CO2 capture by MOFs
Combined experiments and calculations of NEXAFS spectra allow to explore and understand the local signature of molecular adsorption at open metal sites in MOF-74 [J. Am. Chem. Soc. 135, 18183, 2013]
Using a van der Waals corrected functional we demonstrate that a chemical bond analysis and electrostatic considerations can be used to predict trends of CO2 binding affinities to MOFs with transition open metal cations [J. Phys. Chem. Letters 5, 861, 2014]
NEXAFS calculations allow to identify the mechanims by which diamine-appended MOFs chemisorb CO2. Spectral changes arise from a quasi-trigonal carbamate that is hydrogen bonded to an amminium cation (insertion structure in Figure) [Phys. Chem. Chem. Phys. 17, 21448, 2015]
Trends in binding energies of CO2 in two families of MOFs computed using the family of vdW functionals developed by Langreth and Lundvist can be rationalized in terms of enhancement factor and the reduced density gradients around CO2 [J. Phys. Chem. A 116, 4957, 2012]
