Summary: Two new metal-organic frameworks, Cu-MOF and Pd@Cu-MOF, were prepared with copper(ii) paddlewheel secondary building units, exhibiting microporous structures and BET surface areas of 12 m(2) g(-1) and 33 m(2) g(-1) respectively. Gas adsorption experiments showed low uptake of carbon dioxide due to crystal-to-crystal transformation of the MOFs during activation.

Summary: This review focuses on the investigation of various deep eutectic solvents (DESs) for capturing acidic gases in flue gases, summarizing non-functionalized and functionalized DESs for SO2, CO2, and NO capture. New strategies for enhancing absorption capacity, such as introducing a third component to form ternary DESs, are introduced, along with the use of halogen salt hydrogen bond acceptors (HBAs) and functionalized hydrogen bond donors (HBDs) for efficient absorption of SO2 and NO.

Summary: The major gaseous pollutants emitted during the combustion of fossil fuels, energy-intensive production of materials, and waste processing are CO2, SO2, and NOx. The industry and research community are working together to intensify their capture and reduce their emissions in order to meet stricter emission limits. Membrane separation technology, which is energy-efficient and can be combined with other technologies, is a significant application for environmental protection. Different types of membranes with specific functions and unique systems are discussed as promising technologies for flue gas purification.

Summary: This study aims to predict solvent degradation rates in CO2 capture processes using a 30 wt% MEA solvent. A degradation model for MEA is developed and used to predict degradation in full-scale capture processes. The impact of process modifications on degradation is evaluated. The predicted degradation rate is approximately 90 to 150 g MEA/ton CO2 captured, and process modifications can significantly affect the overall degradation rate.

Summary: Carbon dioxide (CO2) capture and storage (CCS) is crucial for enabling the use of fossil fuels while addressing environmental concerns. Among the CO2 capture technologies, postcombustion CO2 capture using solid adsorbents has gained attention due to its noncorrosive nature and low energy demand. However, the design of efficient and stable amine-containing adsorbents for postcombustion CO2 capture is a complex challenge. This article focuses on the development of energy-efficient adsorbents for CO2 capture via temperature swing adsorption (TSA). The key challenges include improving CO2 adsorption capacity, suppressing coadsorption of water, and enhancing the stability of the adsorbents. By combining macroporous silica hosts, alkyl-epoxide-functionalized poly(ethylenimine) (PEI), and phosphate-based oxidative stabilizers, the authors have synthesized adsorbents that exhibit low energy demands and high thermochemical stability. The discussions provide important insights for the practical design of adsorbents for CO2 capture.

Summary: The study found that the density and viscosity of the novel blended PZ-MPDL solvent increased with higher PZ concentration ratio, and decreased with temperature. On the other hand, the physical diffusivity of CO2 decreased with higher PZ concentration ratio, and increased with temperature. Increasing the PZ concentration ratio was shown to improve the CO2 absorption capacity of PZ-MPDL.

Summary: A poly(tetrafluoroethylene) hollow-fiber membrane contactor was used to absorb CO2 in tertiary amine solutions. The study investigated several influential factors and established a mathematical model to calculate CO2 mass transfer flux and concentration distribution. It was found that partially wetted membrane significantly reduced mass transfer, but the predicted values agreed well with experimental results. In addition, an equation for predicting mass transfer coefficients and flux was developed, showing good agreement with experimental values.
