Porous liquid zeolites: hydrogen bonding-stabilized H-ZSM-5 in branched ionic liquids

Abstract

The porous liquid zeolites with permanent porosity could be fabricated by exploiting the hydrogen bonding interaction between the alkane chains of branched ionic liquids and the Brønsted sites in H-form zeolites.

Facilitate Gas Transport through Metal‐Organic Polyhedra Constructed Porous Liquid Membrane

“…collapse of pores. [8] Although the concept was put forward in 2007, the preparation of PLs only remained hypothetically until recently. [9] Based on the intrinsic properties of the components, PLs have been classified into three types.…”

“…By taking advantage of the interactions between porous hosts and bulky solvents, the stability of the prepared PLs can be further improved. [8,13,14] Notably, the porous hosts in type II PLs are discrete porous molecules rather than large porous nanoparticles. As a result, in type II PLs, a concentrated porous host can be achieved.…”

“…[25] In previous study, however, only gravimetric gas solubility date or gas adsorption capacity have been provided. [5,8,12,13] Rare study has been focused on the gas transportation properties through PLs membrane. [6,7,25] Hence, for the first time, we fabricate a graphene oxide supported porous liquid membrane (GO-SPLM).…”

Research Progress of Porous Liquids

“…In the design and synthesis of porous liquids, the preparation of type I porous liquid is usually objective and cannot be designed accurately. For type II porous liquids based on porous cages, the design of rigid porous cages [43] Copyright (2019), with permission from Royal Society of Chemistry. Figure 12.…”

Accelerated robotic discovery of type II porous liquids

“…1 When they were rst proposed in 2007, these materials were hypothetical. Even now, there are only a handful of examples of porous liquids, [2][3][4][5][6] many of which are based on porous organic cages (POCs). 7 POCs are discrete molecules that contain permanent cavities accessible through windows, 7 which makes them useful building blocks for porous liquids, either by rendering them low melting (Type I), 8,9 or by dissolving them in size-excluded solvents (Type II).…”
