| titleOfInvention | Carbon-based oxygen reduction/oxygen precipitation dual-function catalyst and preparation method thereof |
| abstract | The invention discloses a metal-nitrogen-carbon-based oxygen reduction/oxygen precipitation bifunctional catalyst and a preparation method thereof, belonging to the field of preparation of electrocatalysts. The method comprises the following specific steps: in the process of generating high polymer by the compound rich in amino and aldehyde compound, transition metal salt is added as metal source, and the nitrogen-enriched high polymer doped with metal is obtained by reaction at high temperature. And then, carrying out heat treatment carbonization on the obtained high polymer at high temperature, wherein the dispersed nano metal particles can catalyze and generate a large amount of carbon nanotubes with bamboo-shaped morphology, and the metal nanoparticles are wrapped in the carbon nanotubes. The bifunctional catalyst prepared by the method has the characteristics of a large number of transition metal-nitrogen-carbon (M-N-C) active sites, high conductivity, large specific surface area and the like. Meanwhile, the synthesis method is simple, high in repeatability and high in yield, and is beneficial to large-scale production, and the types and the proportions of the doped metals can be adjusted according to requirements, so that the method has obvious economic benefits for developing the bifunctional catalyst of the high-efficiency metal-air battery. |
