Abstract

This communication reports on the preparation of stable and photo-active nano-heterostructures composed of O₂ tolerant [NiFe] hydrogenase extracted from the Aquifex aeolicus bacterium grafted onto hydrophilic CdSe/CdS quantum rods in view of the development of H₂/O₂ biofuel cells. The resulting complex is efficient towards H₂ oxidation, displays good stability and new photosensitive properties.
