▎ 摘  要

NOVELTY - Method for preparing micro-nano materials, comprises (a) introducing the sacrificial carrier into the slurry containing the raw materials and using auxiliary agents to prepare the micro-nano material, and shaping and drying to form a mixture comprising the sacrificial carrier, (b) removing the sacrificial support in the mixture to form a preform having a porous structure, (c) synthesizing the preform to prepare a porous body made of micro-nano materials, and (d) performing a dispersion operation on the porous body to obtain the micro-nano material. USE - The method is useful for preparing micro-nano materials. ADVANTAGE - The method: improves the yield of the micro-nano material. The micro-nano material: has sufficient shape development, little impurity and high quality.
