1. A preparation method of a bimetallic metal-organic frameworks (BMOFs) nanosheet based on a zeolite imidazole framework/materials of institute Lavoisier (ZIF/MIL) topology, comprising the following steps:
dispersing a MOF material of a ZIFs series in an organic phase, and then adding an aqueous phase into the organic phase dispersed with the MOF material of the ZIFs series to obtain a mixture; adding a MOF material of a MILs series into the mixture, sealing the mixture added with the MOF material of the MILs series to stand for 1-5 days (d) to obtain a suspension, filtering the suspension to obtain precipitate, performing centrifugal washing on the precipitate to obtain washed precipitate, drying the washed precipitate to obtain dried precipitate, and performing acetone ultrasonic exfoliation on the dried precipitate to obtain the BMOFs nanosheet based on the ZIF/MIL topology;
wherein the MOF material of the ZIFs series is selected from the group consisting of ZIF-7(Zn), ZIF-8(Zn), and ZIF-67(Co);
wherein the MOF material of the MILs series is selected from the group consisting of MIL-53(Fe), and MIL-101(Fe);
wherein the organic phase is hexane or a mixed solvent of hexane and heptane; and
wherein the aqueous phase is water or a mixed system that is miscible with water.
