title: A changed electrode reaction mechanism between the nano- and macroscales.
abstract: Electrode kinetic data for the electro-reduction of 4-nitrophenol in aqueous solution are compared for bulk silver macro-electrodes and arrays of silver nanoparticles of size 15-50 nm. The electrode kinetics and mechanism change qualitatively and quantitatively.
