| titleOfInvention | Cobalt-nickel bimetallic nitrogen-doped carbon composite material containing single-atom active sites |
| abstract | The invention discloses a preparation method of a cobalt-nickel bimetallic nitrogen doped carbon composite material containing a single-atom active site, which comprises the steps of firstly preparing a ZIF-8 crystal; obtaining ZIF-8@ DNi-ZIF67 crystal, namely MOFs precursor; then calcining the MOFs precursor at high temperature in an inert atmosphere, and naturally cooling to room temperature; and (3) carrying out acid washing treatment on the cooled substance, then washing the substance to be neutral for multiple times, and finally drying the substance. The preparation method utilizes the advantages of the metal organic framework compound precursor, and obtains the target product only by three steps of preparation, calcination and acid washing of the precursor, and the prepared material has high yield, good stability and strong repeatability, meets the requirements of green chemistry, has short preparation period and low requirements on equipment, and has great application potential. The cobalt-nickel bimetallic nitrogen-doped carbon composite material prepared by the method improves the lithium affinity of the material, shortens the diffusion distance of lithium ions and electrons, buffers the volume change in the circulating process, and further effectively improves the electrochemical performance of the material. |
