Summary The direct electrochemical reduction of gaseous CO 2 (dERC) is studied using sterically hindered polyallylamines in solid polymer matrix at room temperature and atmospheric pressure in an electrochemical reactor. It is found that the polymer electrolyte membrane is helpful to regulate the reaction zone in a great extent. Amine in the membrane have strong effect on the Faradaic efficiency and selectivity of the reaction products. The amine group helps to increase the mass transfer of CO 2 at the reaction interface and at the same time regulate the reaction environment by hindering the reactants at the reactive sites.
