CO2 reduction reaction is the electrochemical conversion of carbon dioxide into reduced carbon products at a cathode, driven by an applied potential and competing with hydrogen evolution in the same potential range. Which product appears is set early in the reaction path, where the first intermediate either binds through carbon or through oxygen, and on indium the exposed crystal plane decides that branching: surfaces favouring formate and surfaces favouring carbon monoxide differ only in their geometry [1]. Modifying the surface with an electronegative heteroatom shifts the binding energies of the intermediates and moves the product distribution away from what the unmodified metal gives [2]. Oxygen introduced into a copper-based catalyst has the same redirecting effect on the product spectrum [3]. Three independent handles, the local pH, the electrolyte cation and the surface structure, can be adjusted together to steer selectivity, which is why reported distributions depend so strongly on the cell [4]. Identifying which intermediate is present while the electrode is held at potential is the direct way to test these pictures [5].
