Fenton‐like Reactivity on Fe3O4 Nanozymes Driven by Charge Transfer and Interfacial Water
Small, Volume 22, Issue 3, 13 January 2026.In magnetite nanozymes, subsurface Fe2⁺ donates electrons to H2O2, forming fleeting Fe(IV)═O and •OH species. The process couples charge flow, water‐mediated reactivity, and nanoparticle oxidation in a dynamic Fenton‐like cycle. Abstract Magnetite (Fe3O4) nanoparticles, widely recognized as inorganic nanozymes due to their enzyme‐like catalytic ...
