The development of personal protective equipment (PPE) is essential to control the spread infectious diseases. However, traditional PPE has significant drawbacks, such as a lack antibacterial capacity and nonreusability, which may result in direct or indirect secondary infections. Herein, we propose an octahedral (Fe-O6) Fe-gallate (Fe-GA) metal-organic framework nanozyme with light-enhanced oxidase-like (OXD-like) activity extend use onto nonwoven fabric (Fe-GA/NWF) by hot pressing. Specifically, visible-light-mediated carrier migration OXD-like species synergistically enhance production reactive oxygen species, achieving superior effects without addition any chemical additives. In this case, Fe-GA/NWF spontaneously inactivates over 99.9% real microbial aerosols demonstrates excellent mechanical properties, reusability (15 cycles), biocompatibility. Moreover, can be used ideal platform for KN95 masks clothing extended other substrates. This work provides promising strategy develop self-antibacterial complex environments.
