Coupling CF\u2010NpCu electrodes with affinity\u2010immobilized formate dehydrogenase (FDH) produced 4.4\u2009mM formate after 5\u2009h, a threefold increase compared to the free enzyme system. Although the free enzyme displayed higher intrinsic kinetics, immobilization positioned FDH proximal to the electrode, mitigating diffusional limitations, accelerating NADH turnover, and improving stability.
