文摘

Multiwalled carbon nanotubes grown on gold electrodes manufactured by microtechnology techniques have been used as a platform fororiented and stable immobilization of a Ni-Fe hydrogenase. Microscopic and electrochemical characterization of the system are presented.High-density currents due to H₂ oxidation electrocatalysis, stable for over a month under continuous operational conditions, were measured.The functional properties of this nanostructured hydrogenase electrode are suitable for hydrogen biosensing and biofuel applications.
