Direct comparison of the electrocatalytic oxidation of hydrogen by an enzyme and a platinum catalyst.
It is shown that for molecules of Allochromatium vinosum [NiFe]-hydrogenase adsorbed on a pyrolytic graphite electrode the nickel-iron active site catalyzes hydrogen oxidation at a diffusion-controlled rate matching that achieved by platinum.
