F. Prieto et al., ELECTRODE PROCESSES WITH COUPLED CHEMISTRY - HETEROGENEOUS OR HOMOGENEOUS CHEMICAL-REACTION - THE REDUCTION OF NITROMETHANE IN BASIC AQUEOUS-SOLUTION, Journal of electroanalytical chemistry [1992], 437(1-2), 1997, pp. 183-189
The reduction of nitromethane in aqueous solution (pH 8.3) at Au/Hg ch
annel electrodes is suggested, by means of joint electrochemical ESR a
nd voltammetric measurements, to follow an ECEEE mechanism in which th
e rate determining chemical step is a surface catalysed reaction. Theo
ry characterising heterogeneous ECE (and ECEEE) processes at channel e
lectrodes, studied voltammetrically and with in situ ESR detection, is
reported. (C) 1997 Elsevier Science S.A.
