Electrocatalysis is the study of the effect of the nature of the electrode material on the adsorption and the kinetics of electron transfer between the electrode and the reactant molecule (heterogeneous process). The breaking and formation of chemical bonds in the reactant molecule and/or intermediate reaction are controlled, among other factors, by the adsorption strength with the metal surface. The study of conversion of organic molecules, like glycerol and sorbitol, has been conducted by using of electrochemical techniques coupled with in situ FTIR (Fourier Transform Infrared) and online HPLC (High Performance Liquid Chromatography). However, the mechanism involved in this reaction is still in early phase. Thus, the study of the mechanism of this reaction and the development of materials with higher electrocatalytic activity and selective are extremely important. In this proposal we will investigate the mechanism of the reaction involved during the conversion of glycerol to dihydroxyacetone and sorbitol to glucose/fructose. It will be used Pt and Au single crystal to understand the relation between the nature of the electrode material on the adsorption of the intermediates on the mechanism of the reactions. The products of the reaction will be investigated by online high performance liquid chromatography (HPLC) and by in situ Fourier transform infrared (FTIR). (AU)
