We request 4 days on WISH to study the preferred binding sites and locations of adsorbed gas molecules (CO2,NO2 and D2) within a decorated Al(III)-carboxylate porous framework material (NOTT-300) as a function ofdifferent gas loadings. Constructing new functional frameworks is receiving considerable internationalattention and is a ¿hot topic¿ owing to their potential for gas storage and separation, particularly for thecapture and removal of CO2 and harmful gases. The high resolution and large d-spacing capabilities of WISHmake it ideal for analysing the precise locations of gas molecules within this porous framework.
