Carbon dioxide utilization in catalysis

Abstract The mass scale catalytic transformation of carbon dioxide (CO 2 ) into reduced forms of carbon is an imperative to address the ever‐increasing anthropogenic emission. Understanding the mechanistic routes leading to the multi‐electron‐proton conversion of CO 2 provides handles for chemists to overcome the kinetically and thermodynamically hard challenges and further optimize these processes. Through extensive electrochemical investigations, Prof. J.‐M. Savéant and coworkers have made invaluable electro‐analytical tools accessible to chemists to address and position the electrocatalytic performance of molecular catalysts grounded on a theoretical basis. Furthermore, he has bequeathed lessons to future generations on ways to improve the catalytic activity and the electrocatalytic zone we must target. As a tribute to his accomplishments, we recall here a few aspects on the tuning of iron porphyrin catalysts by playing on electronic effects, proton delivery, hydrogen bonding and electrostatic interactions and its implications to other catalytic systems.
