| titleOfInvention | Growth and binding of multicomponent non noble metal nanoparticle on carbon nanofiber membrane by joule heating process and their fabrication method |
| abstract | The present invention relates to a multi-component crystalline non-noble metal nanoparticle growth through a Joule heating process, a carbon nanofiber membrane bound thereto, and a method for manufacturing the same. In the present invention, a spinning solution containing polyacrylonitrile is applied to carbon nanofibers made through a primary stabilization process in which nanofibers randomly spun through an electrospinning device are carried out in an air atmosphere and a secondary carbonization process in an inert atmosphere. After coating the metal precursor solution, a large-area Joule heating platform is applied and thermal shock is applied to strongly grow and bind non-noble metal nanoparticles with crystallinity such as cobalt-nickel on carbon nanofibers. The embodiment of the present invention has a platform that enables stable current distribution even with a significantly wider sample size compared to the existing Joule heating sample standard (1 cm × 0.2 cm), and is a process specialized for non-noble metals generated at low temperature. It is very different from the small area juul heating of In addition, by growing multi-component crystalline non-noble metal nanoparticles through a short process time of several hundred ms, and at the same time binding on the carbon fiber membrane, it has excellent properties as an electrode such as a lithium-air battery. have The membrane not only has excellent conductivity and high porosity of dimensional structure, but also contains a crystalline non-noble metal nanocatalyst that can promote oxygen generation and reduction reaction. can be used as In particular, the crystalline non-noble metal nanoparticles developed through the present invention are very different from the conventional high-cost noble metal catalysts, and can provide excellent catalytic effects at low cost, and can be manufactured as cathodes of lithium-air batteries even at low cost do. In addition, the large-area synthesis technology of Joule heating proposed in the present invention solves the limitation that samples developed through the existing Joule heating method could not be used independently as electrodes, so it is possible to manufacture them in a size that can be used as a large-area electrode. It is a differentiated material and manufacturing method in this respect. Therefore, it will be utilized as a core technology for the commercialization of an actual lithium-air battery cathode. |
