The performance of heterogeneous catalysts for electrocatalytic CO2 reduction suffers from unwanted side reactions and kinetic inefficiencies at the required large overpotential. However, immobilized CO2 reduction enzymes—such as formate dehydrogenase—can operate with high turnover and selectivity at a minimal overpotential and are therefore ‘ideal’ model catalysts. Here, through the co-immobilization of carbonic anhydrase, we study the effect of CO2 hydration on the local environment and… 


pH effects on the electrochemical reduction of CO(2) towards C2 products on stepped copper
A microkinetic model for CO2 and CO reduction on copper is presented, based on ab initio simulations, to elucidate pH’s impact on competitive reaction pathways and elucidate how reaction conditions can lead to significant enhancements in selectivity and activity towards higher value C2 products.
Toward the Mechanistic Understanding of Enzymatic CO 2 Reduction
Reducing CO2 is a challenging chemical transformation that biology solves easily, with high efficiency and specificity. In particular, formate dehydrogenases are of great interest since they reduce
Interplay of Homogeneous Reactions, Mass Transport, and Kinetics in Determining Selectivity of the Reduction of CO2 on Gold Electrodes
The comprehensive kinetics analysis of the factors defining CDR vs HER on gold electrodes developed here provides an activation-driving force relationship over a large potential window and informs on the design of conditions to achieve desirable high current densities for CO2 to CO conversion while maintaining high selectivity.
Interfacing Formate Dehydrogenase with Metal Oxides for the Reversible Electrocatalysis and Solar‐Driven Reduction of Carbon Dioxide
The strong coupling of the enzyme to the semiconductor gives rise to a new benchmark in the selective photoreduction of aqueous CO2 to formate.
Methanol production via bioelectrocatalytic reduction of carbon dioxide: Role of carbonic anhydrase in improving electrode performance
Electrocatalytic production of methanol from CO2 has recently been studied. This paper focuses on understanding the role of carbonic anhydrase to efficiently facilitate uptake of CO2, which can be
Towards molecular understanding of local chemical environment effects in electro- and photocatalytic CO2 reduction
Substantial progress has recently been made in the general understanding of the interfacial CO2 reduction reaction (CO2RR) in electro- and photocatalysis, but the influence of the local chemical
