(EN) METHOD FOR PREPARING HYDROCARBON-SELECTIVE GAS DIFFUSION ELECTRODES BASED ON COPPER-CONTAINING CATALYSTS
(ZH) 基于含铜的催化剂的烃选择性气体扩散电极的制备技术
Zusammenfassung
(EN)
The present invention relates to a gas diffusion electrode. The gas diffusion electrode comprises a, preferably copper-containing, carrier and a first layer having at least copper and at least one binder, wherein the first layer has hydrophilic and hydrophobic pores and/or channels, further comprising a second layer having copper and at least one binder, wherein the second layer is located on thecarrier and the first layer is located on the second layer, wherein the binder content in the first layer is less than in the second layer. The invention further relates to a method for producing a gas diffusion electrode of this type and an electrolysis cell comprising a gas diffusion electrode of this type.
