Synthesis and enzymatic photo-activity of an O_2 tolerant hydrogenase-CdSe@CdS quantum rod bioconjugate

摘要

This communication reports on the preparation of stable and photoactive nano-heterostructures composed of O_2 tolerant [NiFe] hydro-genase extracted from the Aquifex aeolicus bacterium grafted onto hydrophilic CdSe/CdS quantum rods in view of the development of H_2/O_2 biofuel cells. The resulting complex is efficient towards H_2 oxidation, displays good stability and new photosensitive properties.
