Abstract
Only two enzymes are capable of directly reducing CO2 : the CO dehydrogenase, which produces CO at a [NiFe4S4 ] active site, and the formate dehydrogenase, which produces formate at a W/Mo active site. Both metalloenzymes are very rapid, energy-efficient and specific in terms of product. They have been connected to electrodes with two different objectives. A series of studies used protein film electrochemistry to learn about different aspects of the reactivity of these enzymes (reactivity with substrates, inhibitors…). Another series focused on taking advantage of the catalytic performance of these enzymes to build biotechnological devices, from CO2-reducing electrodes to full photochemical devices performing artificial photosynthesis. Here, we review all these works.Funding Information
