Decoupling Charge Carrier Electroreduction and Enzymatic CO₂ Conversion to Formate Using a Dual-Cell Flow Reactor System.

ABSTRACT: With an efficient atom economy, low activation energy, and valuable applications for fuel cells and hydrogen storage, formic acid (FA) is a useful fuel product to convert CO₂ and reduce emissions. Although metal catalysts are typically used for this conversion, unwanted side reactions remain a concern, particularly when products are attempted to be recovered long-term. In this study, an enzymatic catalyst is used to enable the selective conversion of CO₂ to FA, as a formate ion. A dual-cell flow reactor system is used to first reduce a charge mediator electrochemically (reduction cell), which then activates a catalyst to selectively convert CO₂ to formate (production cell). This approach minimizes enzyme degradation by avoiding direct contact with increased
