Glycerol (GlOH) and ethanol (EtOH) world production have increased exponentially in the last decade. However, the electro-oxidation of EtOH (EOE) has been intensely studied due to the huge availability of this fuel. On the other hand, the interest in GlOH is more recent, growing markedly in the last decade with the increasing in the biodiesel production.In this work, we have comparatively studied the electrocatalytic behavior of PtSn/C NPs on the oxidation of both alcohols by preparing PtSn/C NPs of several compositions. We observed different electrochemical behavior for both molecules on all the catalyst by using cyclic voltammetry and the products/intermediates production/consumption is being monitored by in situ FTIR and long-term chronoamperometry. The products of the reaction during the chronoamperometry are being analysed by HPLC.
