Zeolite-formation mechanisms have long been the subject of intensive study, with most work concentrating on hydrothermal mechanisms. However, non-traditional zeolite syntheses that do not rely crystallisation provided a number new routes to interesting and unexpected materials, but their formation remain poorly understood. Here, we show how simultaneous in situ liquid- solid-state 29Si NMR spectroscopy can reveal mechanism from layered silicate precursor. The study provides evidence for...
Compositionally complex metal-organic frameworks (MOFs) have properties that depend on local structure is often difficult to characterise. In this paper a density functional theory (DFT) computational study of mixed-metal (Al,Sc)-MIL-53, flexible MOF with several different forms, was used calculate the relative energetics these forms and predict NMR parameters can be evaluate whether solid-state spectroscopy differentiate, identify characterise adopted by MOFs composition. The also...
Abstract This study sheds light on the kinetics of crystallisation two Zr-based metal–organic frameworks (MOFs), namely Zr 6 -MOF-808 and -MOF-801, using in situ powder x-ray diffraction (PXRD). Once a room temperature synthesis for MOFs was designed very small scale, successful series PXRD experiments over range 10 °C–40 °C yielded high quality quantitative information both MOFs. These findings indicate importance solubility linker its connectivity: while rate nucleation resulting particle...
