| abstract |
The invention discloses a metal single-atom catalyst and a preparation method thereof. The preparation method comprises: under the protection of an inert atmosphere, dissolving a polyacetylene compound in an aprotic solvent; adding an organic strong Alkali and metal salt precursors are heated and stirred to react, and then solid-liquid separation is performed to obtain the precipitate; the precipitate is washed, dried and ground to obtain the target product. The metal single-atom catalyst of the invention has the advantages of simple preparation method, short synthesis period and strong versatility, and the obtained metal single-atom catalyst has good thermal stability and high metal single-atom loading. |
