The invention discloses a Zn-MOF-derived ordered slit-shaped mesoporous nitrogen-doped carbon nanosheet and a preparation method thereof, slit-shaped mesopores with uniformly distributed pore diameters are arranged in the derived nitrogen-doped carbon nanosheet, and the nitrogen-doped carbon nanosheet has a relatively large specific surface area. According to the preparation method, a copper-doped zinc metal organic framework material (Zn1Cux-MOF) is adopted as a precursor, and the nitrogen-doped carbon nanosheet material with the ordered mesoporous structure is directly synthesized through high-temperature annealing under the condition that a template is not needed. The material is prepared without a template, mesopores of the prepared material are slit-shaped and are highly orderly distributed, and the material has good connectivity and regularity. The method is simple in preparation flow, controllable in process, good in stability, capable of achieving batch production and suitable for macro preparation. 本
