Glycerol electrochemical conversion to more valuable compounds: Mechanistics and kinetics studies

Abstract

This project aims to study and understanding the kinetics and mechanism of the electrocatalytic conversion of glycerol into more valuable commercial compounds. The issue is focused indirectly to the production of biodiesel in the Brazilian energy matrix. The glycerol, as byproduct in the biodiesel production, has led to a significant increase in the supply of this compound in domestic industrial market and hence a drop in the price traded. Thus, we seek in this project, with the aid of electrocatalysis, an alternative way of transforming glycerol into more valuable compounds, such as: glycolic, tartronic acid, glyceraldehyde, oxalic acid, dihydroxyacetone, among other possible products formed during glycerol oxidation. However, very little is known about the conditions in which they can act with selectivity for the production of one or more products mentioned above. Thus, we will work with noble metals electrocatalysts (Au and Pt) to study the variables that inherently act on the system: potential, temperature, pH, and catalysts surface structure. Finally, at the end of this project, we will be able to identify the optimum conditions for the selective production of compounds from glycerol. (AU)
