The present application provides a method for preparing lanthanide fluoride two-dimensional porous nanosheets and belongs to the field of novel materials. In the present application, mixing a water-soluble lanthanide metal salt and an aqueous solution of sodium acetate in a nitrogen atmosphere to obtain a mixed solution, and adding an aqueous solution of fluorine-containing salt to the mixed solution obtained for precipitation reaction to produce lanthanide fluoride two-dimensional porous nanosheets. In the preparation process provided by the present application, no additional surfactant or template agent needs to be added, the pollution of the surfactant to the surface of the prepared material is avoided and the tedious after-treatment steps to template agent are reduced. Accordingly, the large-scale production can be realized, and the lanthanide fluoride two-dimensional porous nanosheets constructed by nanoparticles are prepared in large scale by one step. Moreover, no other organic solvents are required, and the pollution to the environment during the preparation process is avoided.
