Abstract The electrochemical reaction of carbon dioxide (CO 2 ) in aqueous electrolyte solutions is attracting increasing attention for sustainable chemical production. Boron‐doped diamond (BDD) electrodes have been previously shown to be very effective for the stable electrochemical production of formic acid from CO 2 . Typically, the electrochemical production of formic acid by CO 2 reduction (CO 2 R) reaction is performed with a dual‐compartment flow reactor equipped with a membrane separator. The problems caused by the membrane separator, such as scaling‐up, complicated operational control and materials costs can be solved using a membrane free single‐compartment reactor. Here we demonstrate anode reaction control for a single‐compartment CO 2 R flow reactor using a surface‐activated BDD cathode and achieve a Faradaic efficiency for formic acid production of over 70 %.
