LANTHANIDE FLUORIDE TWO-DIMENSIONAL POROUS NANOSHEET, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

A preparation method for a lanthanide fluoride two-dimensional porous nanosheet. A water-soluble lanthanide metal salt is mixed with a sodium acetate aqueous solution in a nitrogen gas atmosphere to obtain a mixture; a fluoride salt-containing aqueous solution is added to the mixture for a precipitation reaction to obtain a lanthanide fluoride two-dimensional porous nanosheet. The preparation process do not require additional surfactants or templating agents, thereby preventing surfactant contamination of prepared material surfaces, and reducing cumbersome templating agent post-treatment steps. The preparation process is suitable for large-scale production, and implements one-step large-scale preparation of lanthanide fluoride two-dimensional porous nanosheets constructed from nanoparticles. The preparation process also does not require other organic solvents, thereby preventing environmental contamination during preparation.
