The charge transfer kinetics of the oxidation of silver and nickel nanoparticles via particle–electrode impact electrochemistry

Author affiliations

Abstract

The electro-oxidation of silver and nickel nanoparticles in aqueous solution was studied via their collisions with a carbon electrode. The average charge passed per impact varies with electrode potential and was analysed to determine that AgNPs display an electrochemically fast (“reversible”) one-electron oxidation, whilst the NiNPs exhibit slow (“irreversible”) 2-electron kinetics. Kinetic parameters are reported.
