Zusammenfassung:The invention discloses a preparation method of an indium-modified multi-layered carbon-based catalyst, which comprises the following steps: S1, reacting a Zn (NO3) 2.6 H2O solution with a dimethylimidazole solution to obtain ZIF-8; s2, mixing and reacting the ZIF-8, an indium salt and a solvent to obtain indium-doped ZIF-8 powder; and S3, calcining the indium-doped ZIF-8 powder, so as to obtain the indium-modified multi-layered carbon-based catalyst. The prepared indium-modified multi-layered carbon-based catalyst presents a multi-layered structure morphology with an uneven surface, single selective electrocatalytic reduction from carbon dioxide to carbon monoxide is realized under the action of the indium-modified multi-layered carbon-based catalyst, and the indium-modified multi-layered carbon-based catalyst is expected to be applied to efficient conversion of carbon dioxide gas. 本发明公开了一种铟改性多重层状碳基催化剂的制备方法,包括如下步骤:步骤S1.Zn(NO3)2·6H2O溶液与二甲基咪唑溶液反应,得ZIF-8;步骤S2.将所述ZIF-8、铟盐和溶剂混合反应,得铟掺杂的ZIF-8粉末;步骤S3.将铟掺杂的ZIF-8粉末煅烧,
