Electrocatalytic activity of hydrogenases at carbon electrodes: hydrogen production via Fe-hydrogenase from Desulfovibrio vulgaris Hildenborough

摘要

Hydrogenases are a class of enzymes that catalyze the reversible oxidation of hydrogen / reduction of protons in the presence of appropriate electron acceptors or donors.Some of them are involved in microorganisms such as sulfate-reducing bacteria.Different hydrogenases have been isolated,and it is remarkable that three types of hydrogenases varying in active center structure,namely [Fe],[NiFe] and [NiFeSe],can co-exist in the same Desulfovibrio vulgaris Hildenborough (DvH) bacterium.
