Metal Corroles for CO2 Reduction/Fixation and Water Oxidation/Reduction(OER/ORR)
Sprache des Vortragstitels:
Electrochemical conversion of CO2 to alcohols is one of the most challenging methods of conversion and storage of electrical energy in the form of high-energy fuels. The challenge lies in the catalyst design to enable its real-life implementation. Herein, we demonstrate the synthesis and characterization of manganese(III) and cobalt(III) corrole complexes, which contain three polyethylene glycol residues attached at the meso-phenyl groups. Electrochemical reduction of the metal complex results in the formation of metal square-planar complexes with electron-rich supernucleophilic metal centers. The metal complexes possess high affinity towards electrophiles, allowing for such electronically configurated metals reactions with carbon dioxide. Herein, we report the potential dependent heterogeneous electroreduction of CO2 to ethanol, methanol and acetic acid of immobilized cobalt and manganese A3-corrole catalyst system.
