Popis: We present a new type of composite material involving the in situ immobilization of tin oxide nanoparticles (SnO2-NPs) within a monolithic metal-organic framework (MOF), the zeolitic imidazolate framework ZIF-8. SnO2@monoZIF-8 exploits the mechanical properties, structural resilience and high density of a monolithic MOF, whilst leveraging the photocatalytic action of the nanoparticles. The composite displays outstanding photocatalytic properties and represents a critical advance in the field of treating toxic effluents and a vital validation for commercial application. Crucially, full retention of catalytic activity was observed after 10 catalytic cycles.
