요약

A process for the selective electrochemical conversion of carbon dioxide into hydrocarbons, namely C2 hydrocarbons is presented. The process is carried out in an electrochemical cell where the cathode is a modified electrode with copper electrodeposits in order to improve the catalytic activity and selectivity of the system. The formation of a mixture of C2 hydrocarbons (C2H4 and C2H6) without methane is successfully obtained on specific higher surface area electrodeposits. Additionally, ethylene is selectively produced in detriment of ethane. The ex-situ copper electrodeposit leads to the steadiness of carbon dioxide reduction process, i.e., the stability of hydrocarbons production due to the weak deactivation of the cathode.

대표청구항

Process for the selective electrochemical conversion of CO2 into C2 hydrocarbons, at room temperature and atmospheric pressure, comprising a two-phase liquid / solid system consisting of an electrochemical cell with an anode and a cathode, characterized by said cathode being modified by copper electrodeposits having either: a. a monolayer porous structure / morphology with craters (1);b. a dendritic morphology orc. a multilayer tridimensional pore structure with different porous sizes (2).
