The present project has as one of the objectives the study of fundamental processes related to the electrocatalysis on electrodes constituted by pure metals (mono and polycrystaline), metal alloys and non-metal electrodes (conducting polymers and oxides). It also has the objective of developing operational systems: modified electrodes, high surface area electrodes, porous electrodes and gas diffusion electrodes, on which the study of catalyzed reactions of fundamental and applied interest will be carried out. Among these, it should be mentioned reactions related to electrochemical energy conversion (oxidation of hydrogen and other fuels, oxygen reduction, etc.), reactions related to environmental protection (electrocatalysis of substances containing sulphur, nitrogen, etc., design of electrochemical sensors) and water electrolysis. These studies are directed to the development of fuel cells and the production of hydrogen and, in general, to the understanding of inorganic and organic electrocatalysis. (AU)
