The unusual combination of characteristics observed for porousl iquids, which are typicallya ssociatedw ith either porous solids or liquids, has led to considerablei nterest in this new class of materials. However,t hese porous liquids have so far only been investigated for their ability to separate ands tore gases.H erein, the catalytic capability of Pt nanoparticles encapsulated within aT ype Ip orousl iquid (Pt@HS-SiO 2 PL)i se xplored for the hydrogenation of several alkenesa nd nitroarenes under mild conditions (T = 40 8C, P H2 = 1atm). The different intermediates in the porousl iquid synthesis (i.e.,t he initial Pt@HS-SiO 2 ,t he organosilane-func-tionalized intermediate, andt he final porousl iquid)a re employeda sc atalysts in order to understand the effect of each component of the porous liquid on the catalysis. For the hydrogenation of 1-decene, the Pt@HS-SiO 2 PL catalysti ne thanol has the fastestr eactionr ate if normalized with respect to the concentrationo fP t. The reaction rate slows if the reactioni sc ompleted in a" neat" porous liquid system,p robably because of the high viscosity of the system.T hese systems may find application in cascade reactions, in particular, for those with mutually incompatible catalysts.

“…[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). Compared with the graphene oxide supported 15-crown-5 membrane, the GO-SPLM shows enhanced permeability of gas (e.g., H 2 , CO 2 , and N 2 ) due to the empty cavity of MOP-18 unit cages in porous liquids that reduces the gas diffusion barrier.…”

Type II porous liquids are demonstrated to be promise porous materials. However, the category of porous hosts is very limited. Here, a porous host metal–organic polyhedra (MOP‐18) is reported to construct type II porous liquids. MOP‐18 is dissolved into 15‐crown‐5 as an individual cage (5 nm). Both the molecular dynamics simulations and experimental gravimetric CO2 solubility test indicate that the inner cavity of MOP‐18 in porous liquids is unoccupied by 15‐crown‐5 and is accessible to CO2. Thus, the prepared porous liquids show enhanced gas solubility. Furthermore, the prepared porous liquid is encapsulated into graphene oxide (GO) nanoslits to form a GO‐supported porous liquid membrane (GO‐SPLM). Owing to the empty cavity of MOP‐18 unit cages in porous liquids that reduces the gas diffusion barrier, GO‐SPLM significantly enhances the permeability of gas.

“…In recent years, porous liquids have emerged as a newly developed type of porous materials, which combine the characteristics of permanent and rigid porosity of porous solids, and the fluidity, rapid heat and mass transfer of liquids, while permanent porosity is not associated with conventional liquids. [7][8][9][10][11][12] Due to their unique physical and chemical properties, porous liquids have broad application prospects in gas adsorption, storage and separation, homogeneous catalysis and other fields. [9][10][13][14][15] According to the composition of the host system in porous liquids, James et al divided the porous liquids into three categories (Scheme 1): type I, type II and type III, respectively.…”

Compared with porous solids, porous liquids have attracted more and more attention due to their unique physical-chemical properties such as permanent porosity, fluidity, rapid heat and mass transfer. They have broad application prospects in the fields of gas adsorption and separation, homogeneous catalysis, and others. Porous liquids are generally divided into three categories that include type I, type II and type III according to the composition of the host system in porous liquids. In this paper, the research progress of porous liquids is briefly reviewed, the examples of synthesis, characterization and application of three types of porous liquids are illustrated in detail. Finally, the main issues and challenges faced by the development of porous liquids are summarized and prospected.
