Simultaneous generation of residue-free reactive oxygen species and bacteria capture for efficient electrochemical water disinfection.

ABSTRACT: Residue-free and highly efficient techniques for drinking water disinfection are urgently needed. Herein, we report an electrochemical water disinfection system equipped with atomically precise Ag₂₈ nanoclusters (NCs) as electrode materials. The deployment of these Ag₂₈ NCs not only provides sufficient electrosorption sites for intelligent microbe enrichment but also ensures high-efficiency dual-mode microbial killing through the in situ electrocatalytic production of residue-free reactive oxygen species (ROS) and the inherent antimicrobial activity of Ag₂₈ NCs. Moreover, the design of the system enables a cyclical "alive microbe capture-killing-dead microbe desorption" process for continuous water disinfection. On this basis, this water disinfection system
