J. Losada et al., ELECTROCATALYTIC REDUCTION OF O-2 AND CO2 WITH ELECTROPOLYMERIZED FILMS OF POLYPYRROLE COBALT(II) SCHIFF-BASE COMPLEXES, Journal of electroanalytical chemistry [1992], 398(1-2), 1995, pp. 89-93
The synthesis of 2-(3-pyrrole-1-yl-propylimino-methyl)-phenol (LH) and
its cobalt complex (CoL(2)) are described. Electrochemical oxidation
of CoL(2) in acetonitrile produces a conducting polymeric film at the
electrode surface. The polymer films are catalytically active in the e
lectroreduction of both oxygen and CO2. In the case of oxygen both the
electrocatalytic activity of the electropolymerized films and the pre
dominant product were dependent on the surface coverage.
