Coating of metal–organic frameworks (MOFs) on flexible substrates is a crucial technology for applications such as purification/separation, sensing, and catalysis. In this work, facile coordination replication strategy was developed to coat various MOFs onto fibrous materials where dense layer an insoluble precursor template, layered hydroxide salt, first deposited fiber substrate via mild interfacial reaction then rapidly transformed into MOF coating in ligand solution at room temperature. Spatiotemporal harmonization solid dissolution crystallization enabled precise the morphology form continuous composed intergrown crystals. The resulting flexible, highly robust, processable MOF/textile composites demonstrated tremendous potential industrially relevant removal organosulfur compound dibenzothiophene from simulated gasoline ammonia capture. This rapid, versatile, eco-friendly, scalable process temperature gives rise new possibilities preparing MOF-coated functional materials.
