▎ 摘  要

NOVELTY - Method for producing a stratified perimorphic framework involves (I) deriving a precursor from a first solution of ions in a process liquid via solventless precipitation, (II) forming a template from the precursor, (III) using the template to form a stratified perimorphic framework and (IV) dissolving the template to form a second solution of ions in the process liquid, such that substantial portions of the ions and the process liquid are conserved and recycled. USE - The method is useful for producing a stratified perimorphic framework. ADVANTAGE - The method can produce three-dimensional architectures constructed from two-dimensional molecular structures economically with reduced waste. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing a perimorphic framework involving deriving a solid precursor from a first stock solution via a solventless precipitation, where the stock solution comprises solvated ions hosted by a process liquid; and substantially separating the derived precursor and the process liquid, where the process liquid is conserved and comprises a conserved process liquid; and treating the precursor to form a template, where the treating involves decomposing a portion of the precursor, and the template comprises a templating surface and a templating bulk; adsorbing an adsorbate on the templating surface to form a perimorphic composite, where the perimorphic composite comprises a perimorph and an endomorph, the perimorph comprises the adsorbate and the endomorph comprising the template, and the adsorbate comprising at least one non-graphenic atomic monolayer; and exposing the endomorph to an extractant solution, and the extractant solution comprises an extractant hosted by the conserved process liquid; reacting a portion of the endomorph with the extractant solution to form solvated ions, the solvated ions hosted by the conserved process liquid, the solvated ions and conserved process liquid together comprising a second stock solution, the second stock solution comprising substantially the same species of ions that comprised the first stock solution; and exfiltrating the second stock solution out of the perimorph into the surrounding process liquid, to form the perimorphic framework, where the framework comprises the adsorbate, the adsorbate comprises a perimorphic wall possessing an average thickness of less than 100 nm, the perimorphic wall substantially replicating a morphology of the templating surface; and internal pores, a portion of the pores substantially replicating a morphology of the templating bulk.
