Studies on the Stability and Deactivation Mechanism of Immobilized Ionic Liquids in Catalytic Esterification Reactions

Zhaoyang Qi et al.

Summary: In this study, solid-supported ionic liquid catalysts (SILs) were prepared and used to investigate their stability in esterification reactions. It was found that MIL-101-[IA-SO3H][HSO4] exhibited higher catalytic activity and lower stability compared to MIL-101-[IA-COOH][HSO4]. The stability of immobilized ionic liquids was found to be primarily determined by the substituents of the ionic liquid cations, which is important for understanding deactivation mechanisms and selecting suitable cations to prevent active site leaching.

Microwave Regeneration and Thermal and Oxidative Stability of Imidazolium Cyanopyrrolide Ionic Liquid for Direct Air Capture of Carbon Dioxide

Yun-Yang Lee et al.

Summary: Understanding the oxidative and thermal degradation of CO2 sorbents is critical for assessing their long-term stability. The degradation pathway of imidazolium cyanopyrrolide, an ionic liquid (IL) used for CO2 capture, was evaluated to understand secondary reactions during absorption-desorption cycles. Analysis showed that the nucleophilicity of the anion encourages radical and S(N)2 mechanisms in degradation. The CO2 capacity of the IL decreased by 50% after 7 days of exposure to O-2 at 80 degrees C, but microwave regeneration at 80 and 100 degrees C prevented measurable degradation.

Density, viscosity, and H2S solubility of N-butylmorpholine bromide iron-based ionic liquids

Chao Li et al.

Summary: This study measured the density and viscosity of N-butylmorpholine bromide iron-based ionic liquids with two iron-morpholine ratios at different temperatures and pressures. The data showed that both density and viscosity decrease with increasing temperature, and the relationship between density and ratio is opposite to that of viscosity. The solubility of H2S in the ionic liquids was also measured and found to increase with decreasing temperature, increasing pressure, and decreasing ratio. The chemical reaction equilibrium constant and Henry's constant were obtained and found to decrease with increasing ratio and decreasing temperature. The absorption of H2S was dominated by chemical absorption at low pressure and gradually shifted to physical absorption with increasing pressure.

Exploring the influence of the type of anion in imidazolium ionic liquids on its thermal stability

Li-Yu Zhang et al.

Summary: In this research, three imidazole ionic liquids were studied for gas adsorption and extraction properties. The thermal stability of the selected ionic liquids was compared, and their decomposition pathways were analyzed. Thermal gravimetric analysis showed that [BMIM][Ac] had the lowest short-term thermal stability, followed by [BMIM][BF4], and [BMIM][Tf2N]. Different kinetic methods were used to calculate the apparent activation energies, showing slight differences between the three ionic liquids. The decomposition mechanism was analyzed using thermogravimetric coupled with Fourier-transform infrared spectrometry. The results revealed that as the thermal stability of the ionic liquids increased, their decomposition mechanisms became more complex.

Current status of CO2 capture with ionic liquids: Development and progress

Wamda Faisal Elmobarak et al.

Summary: Global warming, caused by GHG emissions especially CO2, has become a common environmental issue recently. Current ABTs for CO2 capture have limitations in terms of energy demand, absorption and desorption rates, and environmental sustainability. ILs, with their unique characteristics, have attracted attention as a substitute for existing processes. This review provides an overview of the advancements and challenges in using ILs for CAPCO2, and discusses the mechanisms, properties, characterization, and operating conditions affecting CO2 uptake capacity. It also highlights the impact of cations, anions, and functional groups on CO2 solubility in ILs, as well as the biodegradability and toxicity. The use of IL membrane technology and molecular simulations are also considered. Protic and aprotic ILs have shown excellent efficiency in CO2 capture, and functionalized ILs, supported IL membranes, and reversible ILs have improved the efficiency even under low CO2 partial pressure. More research is needed to understand the chemical breakdown of IL constituents and inform the design of new ILs. This review provides a systematic guideline for ILs manufacturers and engineers in designing high-capacity ILs for CAPCO2.

Summary: Global climate change is worsening and the inefficient reduction of carbon emissions is a major concern for many countries. Membrane separation technology, particularly using two-dimensional (2D) sheet materials like MXene, has gained popularity for CO2 capture due to its operational ease, environmental friendliness, and small footprint. However, the stacking of MXene nanosheets restricts gas transport, decreasing gas permeance. In this study, MXene was hydroxylated to obtain alkaline MXene nanosheets (TCOH) for the preparation of a novel composite membrane (TCOH@Pebax-1657/IL) with high CO2 permeance and selectivity.
