Enhanced performance of molecular electrocatalysts for CO₂ reduction in a flow cell following K⁺ addition.

ABSTRACT: Electrocatalytic CO₂ reduction is a key aspect of artificial photosynthesis systems designed to produce fuels. Although some molecular catalysts have good performance for CO₂ reduction, these compounds also suffer from poor durability and energy efficiency. The present work demonstrates the improved CO₂ reduction activity exhibited by molecular catalysts in a flow cell. These catalysts were composed of a cobalt-tetrapyridino-porphyrazine complex supported on carbon black together with potassium salt and were both stable and efficient. These systems were found to promote electrocatalytic CO₂ reduction with a current density of 100 mA/cm² and generated CO over at least 1 week with a selectivity of approximately 95%.
