  "abstract": "This work investigates two carbon monoxide dehydrogenase (CODH) enzymes immobilised on functionalised carbon nanotube electrodes and describes their behaviour in two deep eutectic solvents, namely glyceline and ethaline. These CODH bioelectrodes achieve CO2 reduction activities in the mA cm-2 range at 150 mV overpotential and retain their electrocatalytic activity in the presence of up to 14% O2, provided that a reducing potential is maintained. The use of deep eutectic solvents as electrolytes further protects the immobilized enzymes from oxygen damage by preventing direct O2 diffusion towards the electrode surface. This dramatically increases the enzyme half-life from 30 min in water to more than 7 h in hydrated glyceline at the expense of a reduced electrocatalytic activity (TOF of 60 s-1 and maximum current density of 0.45 mA cm-2).",
