    摘要： The present invention relates to a carbon dioxide capture and conversion device comprising:
    (A) a first reactor comprising an anion exchange membrane placed between a porous anode and porous cathode, wherein the anode contains or is connected physically or electrically to oxygen evolution and/or carbon dioxide evolution catalyst(s), and the cathode contains or is connected physically or electrically to an oxygen reduction catalyst;
    (B) a second reactor comprising a bipolar membrane placed between a porous anode and porous cathode, wherein the anode contains or is connected physically or electrically to an oxygen evolution catalyst, and the cathode contains or is connected physically or electrically to a carbon dioxide reduction catalyst;
    wherein the porous cathode of the first reactor has at least a fluid inlet able to carry carbon dioxide, air and water, possibly with dissolved species, and the porous anode of the first reactor has at least a fluid inlet able to carry water, possibly with dissolved species, and oxygen,
    the porous cathode of the second reactor has at least a fluid outlet able to carry organic reaction products resulting from carbon dioxide reduction reaction (CO 2 RR), and the porous anode of the second reactor has at least a fluid outlet able to carry water and oxygen,
    wherein the carbon dioxide capture device is configured to transfer fluid exiting the porous cathode of the first reactor to the porous anode of the second reactor, and to transfer fluid exiting the porous anode of the first reactor to the porous cathode of the second reactor.

    摘要： An electrode for use in the electrolysis of water under alkaline conditions, comprising a nickel metal substrate, a ceramic material with a perovskite-type structure comprising an oxide of at least one metal selected from among lanthanides including lanthanum, cerium and praseodymium, where said ceramic material is forming a coating on said nickel metal substrate, and metal nanoparticles are socketed into the said ceramic material. The metal nanoparticles facing the alkaline solution have electrochemical activity, whereas the metal nanoparticles facing the said metal substrate form an anchoring points between the metal substrate and the said ceramic material.
