Abstract
An electrochemical reactor for use with a liquid electrolyte is capable of generating gaseous products. An electrically conducting porous layer that is hydrophilic on the catalyst side and hydrophobic on the gas side are utilized. These different surface properties promote the transport of product gases formed at the catalyst through the porous layer to the gas side. The catalyst is formed from a hybrid Cu2O—CuBr film that has a high selectivity for ethylene gas from reacting CO2 and water in an electrochemical cell.
