An electrolysis electrode and a preparation method therefor, an electrolysis apparatus, and a clothing treatment device. The electrolysis electrode includes a substrate, a transition layer, and an electrode catalytic material layer, and the transition layer is attached to the surface of the substrate, the electrode catalytic material layer is attached to the surface of the transition layer, and the thickness of the transition layer satisfies that: electrons can pass through the transition layer. The transition layer of the electrolysis electrode is relatively thin, so that electrons can pass through the transition layer due to a quantum tunneling effect, and thus the electrocatalytic performance of the electrolysis electrode is basically not affected. Furthermore, the transition layer plays the role of transition connection, and can greatly improve the phenomenon of cracks in the electrode catalytic material layer.

The present application relates to an electrochemical system and method for capturing carbon dioxide, regenerating purified carbon dioxide and/or converting the captured carbon dioxide to biomethane, syngas, formic acid, and combinations thereof. More specifically, the present application relates to an electrochemical cell having an air cathode proton or cation exchange membrane and an abiotic or biotic anode wherein captured carbon dioxide is reduced to carbonates that are regenerated as purified carbon dioxide or transferred to another chemical production module. The regenerated carbon dioxide can be purified, compressed, or stored for later use. The present application includes volatile fatty acids sourced from carbohydrate rich waste. The present application also includes the ability to regenerate caustic absorbents used in initial carbon dioxide capture.
