Abstract
CO2 level increase in the planet is a major concern and utilization, mitigation and transformation of CO2 in useful compounds is of great interest. This chapter points to an alternative electrochemical approach for reducing/making use of CO2 in a “greener” route, using electricity that may be generated from renewable sources (e.g. solar, wind). The most relevant enzymes that can utilize CO2 are described, as well as their electrochemical behaviour. The bioelectrochemical approach (in its different possible systems and configurations) has an enormous advantage in the selection of the reaction products, in mild conditions. Carbon monoxide, hydrocarbons, alcohols, urea and formic acid are detectable products, and the last one has received particular attention in terms of its market added value. Enzymes, multi enzymatic, whole cells, and other bioelectrochemical systems, e.g. microbial fuel cells, for electrosynthesis and CO2 mitigation, are discussed here.
