The electrochemical reaction of carbon dioxide (CO

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
