A Hierarchical Metal-Organic Framework Intensifying ROS Catalytic Activity and Bacterial Entrapment for Engineering Self-Antimicrobial Mask.

ABSTRACT: Leveraging functional materials to develop advanced personal protective equipment is of significant importance for cutting off the propagation of infectious diseases, yet faces ongoing challenges owing to the unsatisfied antimicrobial efficiency. Herein a hierarchically porous cerium metal-organic framework (Ce-MOF) boosting the antimicrobial performance by intensifying catalytic reactive oxygen species (ROS) generation and bacterial entrapment simultaneously is reported. This Ce-MOF presents dendritic surface topography and hierarchical pore channels where the Lewis acid Ce sites are dispersedly anchored. Attributing to this sophisticated nanoarchitecture rendering the catalytic Ce sites highly accessible, it shows a ca. 1800-fold activity enhancement for the catalytic conversion of atmos
