Oxygen reduction on iron-melanin granular surfaces

We report the catalytic activity of iron-eumelanin granular deposits supported on graphite for the oxygen reduction in neutral and alkaline solutions. These deposits contain quinone groups and iron-melanin complexes as revealed by XPS, XANES, EXAFS, and IR spectroscopy. Voltammetric data show that t...
