Electronic-State Programming of Ultrasmall CeO₂ Switches H₂O₂ Activation From Radical to Bio-Inspired Nonradical ¹O₂ Generation for Combating Antibiotic Resistance. [PDF]

Adv Sci (Weinh)
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.
