“…The potential was set at 0.12 V and the electrode was put in contact with the electrochemical solution. This potential was chosen to avoid the continuous glycerol reduction that occurs on Pt when the potential is kept at 0.05 V. [25] …”

We investigate the electrooxidation of glycerol (GlOH) on polycrystalline Pt. The results obtained in the presence of GlOH were compared with those of fresh and disturbed low‐index Pt single crystals [(111), (100) and (110)]. Monitoring of the oxidation currents of GlOH by cyclic voltammetry on the different surfaces revealed that the electrooxidation of GlOH is highly sensitive to the order of the polycrystalline Pt atoms. Interestingly, after being disturbed by the application of voltammetric cycles, the combined responses of the disordered single crystals become similar to that of polycrystalline Pt. The changes in the current values associated with the specific potentials at which each oxidation peak takes place suggest that different ordered domains of Pt oxidize GlOH independently. This simple approach can clearly assist in our understanding of the effect of the order of surface atoms in a given reaction, not only in electrochemical reactions.

“…EG oxidation on Pt can proceed via two different pathways depended on whether C-C bond is broken or not. Behm and co-workers [70] used DEMS to study the external parameters effect, i.e. electrode potential, EG concentration and catalyst loading, on the kinetics of EG electrooxidation at Pt/C.…”

“…This allows the minimization of energy waste and by-products generation. This process has been intensively studied by several authors [1][2][3][4][5][6][7]. In mentioned works, glyceric acid, CO 2 , hydroxypyruvate, tartronic acid, mesoxalic acid, glyceraldehyde, or formic acid are among the main products obtained.…”

Abstract. The reaction pathway for the conversion of glycerol into different products, namely glyceraldehyde, glyceric acid, glycolic acid, mesoxalic acid and tartronic acid was studied by means of electrochemistry. Multiple Pulse Amperometry technique was used to control the potential during the electrooxidation reaction. The estimation of the transfer function was realized on the basis of dynamic models for the oxidation reaction. The equations obtained in the s-domain were expressed in the time domain using Inverse Laplace transformation to describe the variation of glycerol and products concentration.
