Abstract
Less is more: Nickel cyclam complexes are known as efficient catalysts for the electrochemical reduction of CO2 to CO, despite having overvoltages of more than 0.6 V. Incorporating [Ni(cyclam)]2+ into poly(allylamine) through axial coordination of pyridine enables the electrochemical reduction of CO2 to CO near the thermodynamic potential of −0.78 V (vs. Ag/AgCl) at pH 8 with a current efficiency of 90 %.Keywords
