The most recent global health crisis caused by the SARS-CoV-2 outbreak and alarming use of chemical warfare agents highlight necessity to produce efficient protective clothing masks against biohazard threats. However, development a multifunctional textile is still behind supply adequate protection for public. To tackle this challenge, we designed regenerable N-chlorine based biocidal detoxifying textiles using robust zirconium metal–organic framework (MOF), UiO-66-NH2, as chlorine carrier which can be easily coated on fibers. A bleaching converted amine groups located MOF linker active structures. fibrous composite exhibited rapid activity both Gram-negative bacteria (E. coli) Gram-positive (S. aureus) with up 7 log reduction within 5 min each strain well 15 min. Moreover, loaded MOF/fiber selectively rapidly degraded sulfur mustard its simulant 2-chloroethyl ethyl sulfide (CEES) half-lives less than 3 minutes. versatile MOF-based here has potential serve cloth biological
