Bioelectrocatalytic hydrogen production by hydrogenase electrodes

Production of molecular hydrogen by enzyme electrodes based on direct bioelectrocatalysis by [NiFe] hydrogenases from different sources ( Thiocapsa roseopersicina and Desulfovibrio fructosovorans) was investigated. Hydrogen evolution was independently controlled by means of mass spectrometry. A stro...

Zusammenfassung:Production of molecular hydrogen by enzyme electrodes based on direct bioelectrocatalysis by [NiFe] hydrogenases from different sources ( Thiocapsa roseopersicina and Desulfovibrio fructosovorans) was investigated. Hydrogen evolution was independently controlled by means of mass spectrometry. A strong correlation between the cathodic current generated by the hydrogenase electrodes and the rate of hydrogen evolution was demonstrated.
