Sonovoltammetric measurement of the rates of electrode processes with fast coupled homogeneous kinetics: making macroelectrodes behave like microelectrodes

Abstract

Voltammetric measurements of the rates of fast homogeneous chemical reactions coupled to heterogeneous electron transfer at macroelectrodes are demonstrated for two systems, the reductive dehalogenations of ortho-bromonitrobenzene and of 3-bromobenzophenone, by the use of power ultrasound to confer fast mass-transport properties so giving the electrodes the kinetic timescale of microelectrodes.
