Copper(ii) tetrakis(pentafluorophenyl)porphyrin: highly active copper-based molecular catalysts for electrochemical CO2 reduction

We report a highly active copper-based catalyst for electrochemical CO2 reduction. Electrochemical analysis revealed that the maximum turnover frequency for CO2 to CO conversion reached 1 460 000 s(-1) at an overpotential (eta) of 0.85 V. Surprisingly, this value is more than 1 000 000 times higher than those of other reported copper-based molecular catalysts.

Automated summary

A highly active copper-based catalyst for electrochemical CO2 reduction is reported. It achieves a maximum turnover frequency more than 1,000,000 times higher than other reported copper-based molecular catalysts at an overpotential of 0.85 V.
