Toward the Electrochemical Valorization of Glycerol: Fourier Transform Infrared Spectroscopic and Chromatographic Studies
journal contribution
posted on 2016-02-18, 17:58 authored by Yaovi Holade, Cláudia Morais, Karine Servat, Teko W. Napporn, K. Boniface KokohGlycerol electrooxidation reaction
has been investigated by electrochemical,
spectroelectrochemical, and chromatographic methods on palladium–nickel
and palladium–silver nanoparticules supported on carbon Vulcan
XC 72R. These materials, prepared by the so-called “Bromide
Anion Exchange” method, exhibited high activity toward the
glycerol electrooxidation in alkaline medium showing furthermore an
important shift of the onset potential toward low potential values.
Electrolysis coupled with high-performance liquid chromatography (HPLC)
and in situ Fourier transform infrared spectroscopy (FTIRS) measurements
have been used to determine the various compounds generated in the
oxidative conversion of this three hydroxyl groups carbon molecule.
Some products with high added value such as glycerate and tartronate
have been identified. In situ FTIRS results have furthermore shown
the pH decrease in the thin layer near the electrode. These results
will positively serve as guidelines for future works on the potential
use of glycerol in fuel cell devices in a cogeneration of high value
chemicals and energy process.
