Oxidative dissolution of silver nanoparticles by dioxygen: a kinetic and mechanistic study.

We have recently reported a kinetic and mechanistic study on oxidative dissolution of silver nanoparticles (AgNPs) by H(2)O(2). In the present study, the parameters that govern the dissolution of AgNPs by O(2) were revealed by using UV/Vis spectrophotometry. Under the same reaction conditions (Tris-HOAc, pH 8.
