  • Composite multilayered electrocatalysts for COreduction and associated methods
    Patent number: 11824206
    Abstract: The invention relates to a composite multilayer carbon dioxide (CO2) 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.
    Type: Grant
    Filed: March 26, 2019
    Date of Patent: November 21, 2023
