Semiconductor photocatalysts, such as TiO 2 and ZnO, have garnered significant attention for their ability to generate hydroxyl radicals, offering various practical applications. However, the reliance on UV light to facilitate electron-hole separation for hydroxyl radical production poses limitations. In this study, a novel approach is presented utilizing Zn@Fe core/shell particles capable of generating hydroxyl radicals without external energy input. The generation process involves electron donation from Zn to O 2 , resulting in the formation of radical species . O 2 - /H 2 O 2 , followed by Fe-catalyzed conversion of H 2 O 2 into hydroxyl radicals through the Fenton reaction. The release of . OH imparts good antimicrobial and antiviral properties to the Zn@Fe particles. Furthermore, the inclusion of Fe confers magnetic properties to the material. This dual functionality holds promise for diverse potential applications for the Zn@Fe particles.
