Two-dimensional mesoporous superlattices of inorganic materials and method of making and using same

A method of making a composition comprising one or more layer(s) of an inorganic mesoporous material, wherein each individual layer of inorganic mesoporous material comprises 1 to 100 monolayers of inorganic nanocages, the method comprising:

• forming a reaction mixture comprising one or more precursor(s),
• one or more surfactant(s),
• water,
• optionally, one or more pH modifying agent(s), and
• one or more organic solvent(s),
• wherein the one or more surfactant(s) is/are chosen from C8 to C18 alkyltrimethylammonium halides, sodium dodecyl sulfate, N-myristoyl-L-glutamic acid, and combinations thereof and/or the one or more organic solvent(s) is/are chosen from trialkylated benzenes, polymer monomers, hydrophobic solvents, and combinations thereof and/or the one or more organic solvent(s) is/are present at a volume ratio of organic solvent(s) to water of 0.1:1 to 1.5:1 and/or the pH of the reaction mixture is 6 or greater,
• holding the reaction mixture at a time (t1) and temperature (T1);
• and
• optionally, adding a terminating agent to the reaction mixture, whereby an individual layer of inorganic mesoporous material is formed;
• and
• optionally, repeating the forming, holding, and, optionally, holding for each repetition of forming and holding, a desired number of times, whereby one or more additional 15 individual layers of inorganic mesoporous materials are formed;
• and
• optionally, stacking the individual layer and additional individual layer(s), wherein the composition is formed.
