Efficient Electrochemical CO2/CO Interconversion by an Engineered Carbon Monoxide Dehydrogenase on a Gas-Diffusion Carbon Nanotube-Based Bioelectrode


We have developed an enzymatic process that achieves high performance towards the reversible electrochemical CO2-to-CO conversion under mild conditions with low overvoltage. Using an engineered Carbon Monoxide Dehydrogenase (CODH), these results make it possible to envision their use both for the reduction of CO2 and for the oxidation of CO, in the context of syngas purification processes and the production of valuable chemicals or fuels from CO2.
