COMPOSITE MULTILAYERED ELECTROCATALYSTS FOR CO2 REDUCTION AND ASSOCIATED METHODS

The invention relates to a composite multilayer carbon dioxide (CO) reduction catalyst, comprising a catalyst layer comprising at least one metal compound, the catalyst layer having opposed first and second sides; a hydrophobic gas-diffusion layer provided on the first side of the catalyst layer; a current collection structure provided on the second side of the catalyst layer. The metal is preferably copper. The invention also relates to a method for electrochemical production of a hydrocarbon product, such as ethylene, using said catalyst.
