Turning the FeFe hydrogenase from <i>Clostridium beijerinckii</i> into an efficient H₂ oxidation catalyst using a redox-active matrix.

ABSTRACT: Hydrogenases are Nature's sustainable and efficient catalysts for the conversion between H⁺ and H₂. The obstacles that prevented their use as H₂ oxidation catalysts in fuel cells are being removed one by one, thanks to the continuous discovery of hydrogenases that have unexpected catalytic properties, the development of new methods for their scalable production and matrices that protect them. Obtaining an efficient biohybrid electrode that is scalable and robust under a large range of experimental conditions is still challenging. The FeFe hydrogenase of Clostridium beijerinckii is a very active catalyst of H₂ evolution and can be handled under O₂, and its production can potentially be scaled up. However, it was believed that it
