    摘要: A process for electrochemical reduction of carbon dioxide and water forming carbon monoxide and hydrogen comprising the steps of; providing a metal substrate formed of a metal having a low carbon monoxide bonding strength; forming a self-assembled monolayer bonded to the metal substrate wherein the self-assembled monolayer includes an organic ligand having a surface end having a reactive group bonded to the metal substrate and an opposing end including an organic functional group regulating a ratio of reaction products; contacting carbon dioxide and water with the electrode having the self assembled monolayer forming carbon monoxide and hydrogen; wherein a selectivity of reaction products of carbon monoxide and hydrogen produced by the electrode is regulated relative to a bare metal substrate.
