Abstract

The glycerol is a coproduct of the biodiesel production. Experts predict that soon the big volumes of glycerol come from the biodiesel production will exceed the actual world demand. In this way, there is an effort towards to find new applications to the glycerol. The Group of Electrochemistry of the University of São Paulo proposes the utilization of glycerol in direct glycerol fuel cells with the aim to generate energy. The objective of the present project is to study the mechanism of the electro-oxidation reaction of the glycerol on single and polycrystalline model catalysts (for example: Pt, Au) in acid, neutral and alkaline medium. This knowledge is fundamental to the development of efficient catalysts and to the improvement of the electrochemical process to the application of the glycerol in direct glycerol fuel cells. (AU)
