| titleOfInvention | Preparation method and use method of high-dispersion copper-zinc catalyst for carbon dioxide reduction |
| abstract | The invention provides a preparation method and a use method of a high-dispersion copper-zinc catalyst for carbon dioxide reduction. The method comprises the steps of firstly synthesizing a copper oxide nanoparticle precursor with uniform particle size, then preparing a ZIF-8 MOFs-coated copper oxide composite nanomaterial through liquid phase synthesis, and roasting at programmed temperature to obtain the nitrogen-doped carbon skeleton-coated high-dispersion copper-zinc catalyst. The method is characterized in that copper oxide nanoparticles are added in the process of preparing the ZIF-8, so that the copper oxide nanoparticles are uniformly loaded in MOFs in situ, high-dispersion zinc coated by a carbon framework is obtained after high-temperature calcination, reduction and redispersion of copper are realized, a large amount of pyridine nitrogen also exists in the carbon framework, a novel preparation technology of a high-dispersion copper-zinc catalyst supported by the carbon framework doped with the pyridine nitrogen is developed, the catalyst is applied to the reaction of preparing carbon monoxide by carbon dioxide hydrogenation reduction, the catalyst has excellent catalytic activity, and the existence of high-dispersion copper-zinc active sites and a large amount of pyridine nitrogen has great promotion effect on the promotion of the catalytic activity. |
