Although there has been a wealth of research focused on strategies for oxidation of methanol completely to carbon dioxide, the reverse electrocatalytic reaction of producing methanol from carbon dioxide has shown interest but, as of yet has lacked efficiency. This project focuses on understanding the possible role of carbonic anhydrase to efficiently facilitate uptake of CO2 , which can be the rate determining step in producing fuels from carbon dioxide. The three oxidoreductase enzymes responsible for CO2 reduction to methanol are formate dehydrogenase, formaldehyde dehydrogenase, and alcohol dehydrogenase. This synthetic pathway for methanol production is coupled to a poly(neutral red) modified electrode that continually regenerates the NADH coenzyme so the process can run continuously. We have found that while the dehydrogenases alone can achieve reduction of carbon dioxide, the process is accelerated by the addition of the carbonic anhydrase. As researchers try to increase the efficiency of electrochemical production of fuels, carbonic anhydrase will likely have a critical role.
