Enhancement of the oxygen reduction reaction electrocatalytic activity of metallo-corroles using contracted cobalt( iii ) CF 3 -corrole incorporated in a high surface area carbon support

Molecular oxygen reduction reaction catalysts based on metallo-corrole with the smallest meso -substituent reported to-date, Co( iii )CF 3 -corrole, was synthesized and compared to the well-studied Co( iii )tpfcorrole when adsorbed on a high surface area carbon support. This study shows the improved...

Summary:Molecular oxygen reduction reaction catalysts based on metallo-corrole with the smallest meso -substituent reported to-date, Co( iii )CF 3 -corrole, was synthesized and compared to the well-studied Co( iii )tpfcorrole when adsorbed on a high surface area carbon support. This study shows the improved electrocatalytic performance with the new corrole, attributed to its unique compact structure, which enables surface interactions in favor of lowering the reaction overpotential by 70 mV.
