Deciphering Metal-Organic Framework Synthesis from Hydroxy Double Salts: In-Situ Insights via Synchrotron X-ray Diffraction and Absorption Spectroscopy.

ABSTRACT: Developing rapid room-temperature synthesis is key to sustainable manufacturing of metal-organic frameworks (MOFs). Using layered compounds such as hydroxy double salts (HDSs) as precursors significantly promotes the reaction kinetics and lowers the required synthesis temperature. However, limited understanding of the reaction mechanism impedes the further exploration of new routes for MOF synthesis. Here, we report for the first time the use of combined in-situ synchrotron X-ray diffraction and X-ray absorption spectroscopy to monitor the dynamic processes to form MOFs in solution. The conversion from a (Zn,Co) HDS to a mixed-metal zeolitic imidazolate framework-8 (mmZIF-8) was chosen as our model reaction. Time-resolved diffraction patterns exclude the presence of intercalated HDS struct
