ELECTROLYZER AND MEMBRANES

摘要

An electrochemical device converts CO2 into various products such as CO, HCO-, H2CO, (HCO2)-, H2CO2, CH3OH, CH4, C2H4, CH3CH2OH, CH3COO-, CH3COOH, C2H6, (COOH)2, (COO-)2, H2C=CHCOOH, and CF3COOH. The device is made up of an anode, a cathode, and a Helper Membrane. In some embodiments, the device can also contain a catalytically active element. In some embodiments, the device is able to achieve a faradaic efficiency above 50% and CO2 conversion current density over 20 mA/cm2 at a cell voltage of 3.0 V. In some embodiments, the Helper Membrane comprises a polymer containing an imidazolium ligand, a pyridinium ligand, or a phosphonium ligand.
