Abstract


In this research, the effect of temperature and conversion of glycerol was studied by using cyclic voltammetry technique. The results showed that this reaction occurred following to diffusion mechanism with activation energy approximately of 3.44 (kcal/mol). Moreover, conversion of glycerol by electrolysis using Pt-Pd-Ni/C catalyst also was investigated and compared with the case of using pure Pt. Electrolysis process with electrode Pt-Pd-Ni/GC and pure Pt-was occurred by the first order and this result was well-suit with the previous study about the reaction mechanism of glycerol electro-oxidation process. Obtained results showed that conversion of glycerol on the trimetallic catalyst was higher than the pure Pt.
