Abstract
The present invention relates to a novel approach of obtaining a gas diffusion electrode (GDE), the gas diffusion electrodes obtained using said method and the use thereof in the electrocatalytic conversion of gaseous reactants into economically interesting reaction products. The GDEs obtained using the method of the present invention are particularly useful in the electrochemical of gaseous reactants such as CO2, H2, N2, or O2 into bulk chemicals and fuels such as Syngas, Formic Acid, Methanol, Ethanol, Ethane, Ethylene, Methane, Ammonia, and the like.
Claims8
A Gas Diffusion Electrode (GDE) comprising a Catalytic Activated Gas Diffusion Layer (CAGDL), wherein the CAGDL comprises an electrochemically fully activated Gas Diffusion Layer (GDL) comprising a catalytic material homogenously distributed within the fully activated GDL, the fully activated GDL further comprising a porous binder material, wherein the catalytic material is present within the activated GDL in the absence of a conductive carbon support for the catalytic material, and in the absence of a current collector or current distributor, and wherein the catalytic material comprises a metal selected from Sn, Cd, Zn, Pb, Sb, Bi, or a eutectic composition comprising two or more of the metals and is present withing the fully activated GDL as recrystallized nanostructured particles.
