Abstract: A method and apparatus is provided for the electrochemical reduction of carbon dioxide to formate and formic acid. One embodiment features a three-compartment reactor which houses: a gas compartment; a catholyte compartment, which contains a porous cathode having a tin-based catalyst; and an anolyte compartment, which contains an anode having a mixed metal oxide catalyst. Further embodiments include a method for depositing tin onto a porous cathode, tin-zinc cathodes, a reaction method using an acidic anolyte, and pulsed polarization to extend reactor runtimes.
