The invention relates to a preparation method of a three-dimensional ordered mesoporous MOF material. The preparation method comprises the following steps of: the step A, preparing
polystyrene PS microspheres; the step B, preparing a three-dimensional ordered mesoporous zif8 material; B1, dispersing a proper amount of
zinc nitrate hexahydrate into
methanol to obtain a solution A, dispersing a proper amount of 2-methylimidazole into
methanol to obtain a solution B, adding the solution B into the solution A, adding 1-2g of PS microspheres obtained in the step A for uniform stirring, sealing, standing and aging; B2, sequentially adopting
methanol and
ethanol as solvents after centrifuging, and respectively washing for three times;
drying the
solid and liquid to obtain a 3Dzif8 material with an ordered mesoporous structure; the step C, carbonizing the 3Dzif8 material; putting the 3Dzif8 material in the step B2 into a tubular furnace, performing carbonizing at a high temperature in Ar / H2
mixed gas, and performing cooling to a
room temperature to obtain the CNT-3Dzif8. According to the preparation method, the 3D ordered zif8 material is prepared by adoption of a template method, and thethree-dimensional ordered ZnS material is prepared after
carbonization, so that the electrochemical performance of the
lithium ion battery is improved.
