Here the authors show how the production of nano-ZIF-8 can be conducted at the 1kg scale in an economical manner through the intermediate phase ZIF-L. The production of MOFs at large scale in a sustainable way is key if these materials are to be exploited for their promised widespread application. Much of the published literature has focused on demonstrations of preparation routes using difficult or expensive methodologies to scale. One such MOF is nano-zeolitic imidazolate framework-8 (ZIF-8) - a material of interest for a range of possible applications. Work presented here shows how the synthesis of ZIF-8 can be tracked by a range of methods including X-ray diffraction, thermo gravimetric analysis and inelastic neutron scattering - which offer the prospect of in-line monitoring of the synthesis reaction. Herein we disclose how the production of nano-ZIF-8 can be conducted at scale using the intermediate phase ZIF-L. By understanding the economics and demonstrating the production of 1 kg of nano-ZIF-8 at pilot scale we have shown how this once difficult to make material can be produced to specification in a scalable and cost-efficient fashion.2022http://zaguan.unizar.es/record/11211910.1038/s42004-021-00613-zhttp://zaguan.unizar.es/record/112119oai:zaguan.unizar.es:112119info:eu-repo/grantAgreement/EC/H2020/760944/EU/Advanced MEMBranes and membrane assisted procEsses for pre- and post- combustion CO2 captuRe/MEMBERThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 760944-MEMBERCommunications Chemistry 5 (2022), 18 [10 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
