Direct electrochemistry of an [FeFe]-hydrogenase on a TiO2 electrode

Chem Commun (Camb). 2011 Oct 14;47(38):10566-8. doi: 10.1039/c1cc14535e. Epub 2011 Aug 24.

Abstract

[FeFe]-hydrogenases are efficient natural catalysts that can be exploited for hydrogen production. Immobilization of the recombinant [FeFe]-hydrogenase CaHydA was achieved for the first time on an anatase TiO(2) electrode. The enzyme is able to interact and exchange electrons with the electrode and to catalyze hydrogen production with an efficiency of 70%.
