Title Gas adsorption and binding properties of metal organic frameworks
Abstract This thesis describes the design, synthesis and extensive characterisation of adsorbate gas interactions of two porous Metal Organic Framework materials, constructed from the organic ligand molecule 3,3’,5,5’-biphenyl tetracarboxylic acid, and Bi111 and In111" ions respectively. Chapter 1 forms a general introduction to the global problems posed by the decrease of fossil fuel reserves, increase of pollution, and global warming, the structural and properties of MOFs, and the role they play within these fields. Particular attention is given to the determination of the nature of the binding interactions of gas molecules of interest within these materials, with the aim of designing future materials with improved properties. Chapter 2 presents the first highly porous MOF synthesised from the heavy Bi111 metal ion and investigates the density, porosity and gas adsorption properties of this material. Insight into the packing and binding of gas molecules within this material are gained by computational investigations. Chapter 3 discusses an In111 MOF, isostructural to NOTT-300 (Al), and the adsorption of the fuel gases H2 and CH4 within this material. The stepwise binding positions of these gases within this material are determined by Neutron Powder Diffraction experiments and the methane binding interactions with this material are studied computationally and by Inelastic Neutron Scattering. Chapter 4 investigates the flue gas sorption and separation properties of NOTT-300 (In) by studying the N2, CO2 and SO2 adsorption, selectivity and binding interactions of this material. The binding positions of CO2 and SO2 within NOTT-300 (In) are determined by single crystal and powder X-Ray diffraction respectively, and the framework interactions and separation properties studied by infrared spectroscopy. Interactions of N2, CO2 and SO2 with this material are further investigated by INS spectroscopy.
