Abstract

The kinetic characteristics of oxygen reduction on the surface of core–shell type nanocomposites FeFe2O4 & Ag0 are considered in the context of the certain catalytic cycle, which may occur due to electrochemical interaction between core and shell moiety. Being synthesized under different initial concentrations of Ag+ in the incubation medium, metal silver nanoclusters on the surface of magnetite core can form a layer varying from islet-like structures to aggregated spherical porous shell, thereby altering the electrocatalytic activity of the nanocomposite. Consequently, the ability for reactive oxygen species generation can be predetermined to specify potential biological activity of the nanocomposite through its interference with free radical metabolism.
