What a catch! Basic ionic liquids (ILs) based on phosphonium hydroxide derivative can be tuned for CO2 capture by varying the weak proton donors, which have different pKa values. The stability, absorption capacity, and enthalpy of ILs could easily tuned: best IL has good stability (>300 °C), energy saving (ca. 56 kJ mol−1), equimolar capability.
CO2 capture: Protic ionic liquids (PILs) from a superbase and fluorinated alcohol, imidazole, pyrrolinone, or phenol were designed to capture based on the reactivity of their anions CO2. These PILs are capable rapid reversible about one equivalent CO2, which is superior those sorption systems traditional aprotic ILs.

A general strategy for the synthesis of porous, fluorescent, triazine-framework-based membranes with intrinsic porosity through an aromatic nitrile trimerization reaction is presented. The essence this lies in use a superacid to catalyze cross-linking efficiently at low temperature, allowing porous polymer membrane architectures be facilely derived. With functionalized triazine units, exhibits increased selectivity separation CO(2) over N(2). good ideal CO(2)/N(2) 29 ± 2 was achieved...

An extremely high capacity (>3.5 mol/mol) and excellent reversibility (28 recycles) were achieved by tuning interaction between basic acidic SO2. Spectroscopic investigations quantum-mechanical calculations showed that such originates from multiple sites These tunable with offer significant improvements over commonly used absorbents, indicating promise industrial...

An extremely high capacity up to 1.60 mol per IL and excellent reversibility were achieved introducing a nitrogen‐based interacting on the phenolate imidazolate anion. Quantum‐chemical calculations, spectroscopic investigations, calorimetric data demonstrated that multiple‐site between two kinds sites in anion resulted superior...
Abstract Phenolic ionic liquids for the efficient and reversible capture of CO 2 were designed prepared from phosphonium hydroxide substituted phenols. The electron‐withdrawing or electron‐donating ability, position, number substituents on anion these correlated with physicochemical properties liquids. results show that stability, viscosity, ‐capturing ability significantly affected by substituents. Furthermore, relationship between decomposition temperature, ‐absorption capacity, basicity...
Imidazolium-based ionic liquids continue to attract interest in many areas of chemistry because their low melting points, relatively viscosities, ease synthesis, and good stabilities against oxidative reductive conditions. However, they are not totally inert under conditions due the intrinsic acidity hydrogen at C-2 position imidazolium cation. In this work, was exploited combination with an organic superbase for capture CO2 atmospheric pressure. During absorption CO2, imidazolium-based...
Integrated sorption systems consisting of 1 : mixtures an alcohol-functionalized ionic liquid and a superbase were found to be effective for CO2 capture under atmospheric pressure, eliminating the use volatile n-alkanols or water. Conversely, by using current approach, there is no longer requirement maintaining scrupulously dry conditions. The effect structure, choice superbase, their relative ratios, temperature, reaction time on absorption release investigated. Our results demonstrate that...
Two kinds of dual functionalized ionic liquids with ether-functionalized cations and tetrazolate anions were designed, prepared, used for SO2 capture, which exhibit an extremely high capacity excellent reversibility through a combination chemical physical absorption.
You can have your cake and eat it too: A "dual-tuning" strategy for improving the capture of SO2 was developed by introducing electron-withdrawing sites on anions to produce several kinds functionalized ionic liquids. Those with a halogen group exhibited improved performance over their non-halogenated counterparts, leading highly efficient reversible capture. As service our authors readers, this journal provides supporting information supplied authors. Such materials are peer reviewed may be...
CO2 capture and storage (CCS) has attracted worldwide interest because makes a significant contribution to global warming climate change as major greenhouse gas. Ionic liquids are promising absorbents for carbon due their negligible vapour pressures, wide liquid range, high thermal stabilities tunable properties.
