Potentiodynamic Polarization Studies of Glycerin in Platinum Electrodes

Abstract

<span><p class="TTPAbstract"><span lang="EN-US">A three electrode system was used for the analysis of potentiodynamic polarization studies of glycerin in platinum electrodes. Particular attention was devoted to the estimation of diffusion coefficient of glycerin in platinum electrodes by the use of electrochemical techniques such as the sweep of the potential. Cyclic voltammograms were recorded at different sweep rates (0.01 and 0.07 V·s-1). Randles-Sevcik equation was taken into consideration and a linear relationship was found between </span><span lang="DE">the peak current and the square root of the voltage sweep rate from where the value of diffusion coefficient could be determined. The values of Tafel constants, useful in the understanding of electrochemical reaction kinetics are also reported in the present paper.</span><b><span lang="EN-US"><o:p></o:p></span></b></p>

Pd/CNT Catalysts for Glycerol Electro‐oxidation: Effect of Pd Loading on Production of Valuable Chemical Products

“…Although Pt is the most active electrocatalyst for GOR in acidic media, it also suffers serious problems due to poisoning of Pt electrode . Meanwhile in alkaline medium, palladium and palladium based alloys have proven to be the most efficient and feasible substitutes to Pt . Moreover, it was found that the catalyst support played an effective role towards overall distribution of the metal nanoparticles .…”

Modeling of the partial oxidation of glycerol by estimation of its transfer function

“…Electrochemical experiments were performed as described in [9]. Samples were taken at specific intervals of time and the analysis of the glycerol oxidation products was performed using a recent published method [10].…”
