Voltammetry in the presence of ultrasound: Surface and solution processes in the sonovoltammetric reduction of nitrobenzene at glassy carbon and gold electrodes

Abstract:

The application of power ultrasound in electrochemistry may promote or usefully modify electrode reactions. In the work reported here the four-electron reduction of nitrobenzene in alkaline (pH 13) aqueous media was studied as a model system. The electrochemical reduction is known to follow a complex mechanism [E. Laviron, A. Vallat and R. Meunier-Prest, J. Electroanal. Chem., 379 (1994) 427], involving protonations as well as a dehydration step; both surface and solution pathways for this re...
