Abstract
A method for preparing two-dimensional (D) ordered mesoporous nanosheets by inorganic salt interface-induced assembly includes the following steps: carrying out, by using a soluble inorganic salt as a substrate and an amphiphilic block copolymer as a template, uniform mass diffusion of a target precursor solution at an inorganic salt crystal interface through vacuum filtration or low-speed centrifugation; forming a single-layer ordered mesoporous structure by using the solvent evaporation-induced co-assembly (EICA) technology; and promoting, through gradient temperature-controlled Ostwald ripening, the evaporation and induced formation of an organic solvent, and removing the template in Nto obtain aD single-layer ordered mesoporous nanosheet material. The assembled nanosheet material has a large pore size, regular spherical pores and orderly arrangement. By changing the type of the precursor, a variety of mesoporous metal oxides, metal elements, inorganic non-metal nanosheets are synthesized.
