The invention provides a method for preparing a two-dimensional porous nanosheet of lanthanide fluoride, which belongs to the field of new materials. In the present invention, in a nitrogen atmosphere, water-soluble lanthanide metal salts and sodium acetate aqueous solution are mixed to obtain a mixed solution; an aqueous fluorine-containing salt solution is added to the mixed solution to undergo a precipitation reaction to obtain a two-dimensional porous lanthanide fluoride Nanosheets. The preparation process provided by the present invention does not need to add additional surfactants or templates, avoids the pollution of surfactants to the surface of the preparation materials and reduces the cumbersome post-treatment steps of templates, and can carry out large-scale production, realizing the one-step large-scale preparation Two-dimensional porous nanosheets of lanthanide fluorides constructed of nanoparticles; no other organic solvents are required to avoid environmental pollution during the preparation process. |
