We request 5 days on WISH to study the preferred binding sites and locations of adsorbed gas molecules (CO2, SO2, C2D2, C2D4, and D2) within a decorated Al(III)-carboxylate porous framework material (NOTT-300) as a function of different gas loadings. Constructing new functional frameworks is receiving considerable international attention and is a ¿hot topic¿ owing to their potential for gas storage and separation, particularly for the capture and removal of CO2 and harmful gases. The high resolution and large d-spacing capabilities of WISH make it ideal for analysing the precise locations of gas molecules within this porous framework.
