Engineering Electro- and Photocatalytic Carbon Materials for CO₂ Reduction by Formate Dehydrogenase.

ABSTRACT: Semiartificial approaches to renewable fuel synthesis exploit the integration of enzymes with synthetic materials for kinetically efficient fuel production. Here, a CO₂ reductase, formate dehydrogenase (FDH) from Desulfovibrio vulgaris Hildenborough, is interfaced with carbon nanotubes (CNTs) and amorphous carbon dots (a-CDs). Each carbon substrate, tailored for electro- and photocatalysis, is functionalized with positive (-NHMe₂⁺) and negative (-COO^-) chemical surface groups to understand and optimize the electrostatic effect of protein association and orientation on CO₂ reduction. Immobilization of FDH on positively charged CNT electrodes results in efficient and reversible electrochemical CO₂ reduction via d
