Oxygen Atom Transfer Reactions of Colloidal Metal Oxide Nanoparticles.

Redox transformations at metal oxide (MO)/solution interfaces are broadly important, and oxygen atom transfer (OAT) is one of the simplest and most fundamental examples of such reactivity. OAT is a two-electron transfer process, well-known in gas/solid reactions and catalysis. However, OAT is rarely directly observed at oxide/water interfaces, whose redox reactions are typically proposed to occur in one-electron steps.
