Resumen
Electrode modified for the electrocatalytic oxidation of alcohols. The present invention provides a complex of a divalent or trivalent metal of the periods 4, 5 and 6 and a tetradentate ligand of the formula (I) Wherein r 1 , r 2 , r 3 and r 4 are independently a hydrogen atom or a hydroxyl group, with the proviso that two of r 1 , r 2 , r 3 and r 4 are a hydroxyl group in ortho or para position and with the proviso that the metal is not copper. Also, the invention provides a modified electrode comprising a conductive substrate coated with a polymeric film of said complex; as well as a method for the preparation of said electrode and the use thereof to catalyze the electrooxidation of short chain aliphatic alcohols.
