Abstract
The NiFe hydrogenase from Allochromatium vinosum can be adsorbed at a graphite surface, at which it catalyses hydrogen oxidation at rates comparable to a Pt catalyst, but with much greater CO tolerance. The turnover number, exceeding 10,000/sec at 45 C (including electron transfer along an internal ray of Fe-S centres) makes this a unique system for studying many aspects of biological redox catalysis and interfacial electrochemistry, and raises exciting possibilities for future energy production. This project will examine the mechanisms of active site catalysis and long- range electron transfer, the adsorption of enzyme on carbon surfaces, and the feasibility of producing a stable and efficient catalytic anode.
