| titleOfInvention | A hollow spherical carbon-based catalyst derived from aqueous ZIF and its preparation method and application |
| abstract | The invention discloses a hollow spherical carbon-based catalyst derived from an aqueous ZIF, a preparation method and application thereof. First, aqueous solutions A and B containing zinc salt and organic ligands are prepared respectively at room temperature; The solution is slowly poured into solution B and mixed, and then the chelating agent is added to mix thoroughly; the competitive coordination between the chelating agent and the organic ligand can be etched in situ during the formation of ZIF, and finally a hollow structure with stable structure is formed. porous structure. The precipitate was collected by centrifugation, dried and treated at high temperature in an inert atmosphere to obtain a multi-element doped hollow porous carbon catalyst. The method solves the technical problem that the preparation process of the hollow structure catalyst is complicated, and the preparation process is simple and environmentally friendly. The thickness of the prepared hollow carbon-based catalyst carbon shell can be adjusted in the range of 2-10 nm. The prepared catalyst has excellent acid and alkaline oxygen reduction activity and stability, as well as high zinc-air battery performance. |
