Defect engineering of Zr-based MOFs

The targeted incorporation of defects in engineered materials is at the hearth of material science. In particular, in metal-organic frameworks (MOFs) a relatively new porous materials, defects seem to play a key role in synthetic methods and can become an important additional tool for designing MOFs with enhanced reactive properties. However, establishing a clear structure-property relationship remains a challenge still today. In this work, the incorporation of defects via the modulation approach into different Zr-based MOFs was studied. The system investigated, i.e. UiO-66 and MOF-808, were then characterized by water adsorption, high pressure PXRD (HPPXRD) and variable temperature XRD (VTXRD) in order to uncover the effect of defects in this material properties.
