Porous metal–organic frameworks have emerged to resolve important challenges of our modern society, such as CO2 sequestration. Zeolitic imidazolate frameworks (ZIFs) can undergo a glass transition to form ZIF glasses; they combine the liquid handling of classical glasses with the tremendous potential for gas separation applications of ZIFs. Using millimetre-sized ZIF-62 single crystals and centimetre-sized ZIF-62 glass, we demonstrate the scalability and processability of our materials. Further, following the evolution of gas penetration into ZIF crystals and ZIF glasses by infrared microimaging techniques, we determine the diffusion coefficients and changes to the pore architecture on the ångström scale. The evolution of the material on melting and processing is observed in situ on different length scales by using a microscope-coupled heating stage and analysed microstructurally by transmission electron microscopy. Pore collapse during glass processing is further tracked by changes in the volume and density of the glasses. Mass spectrometry was utilized to investigate the crystal-to-glass transition and thermal-processing ability. The controllable tuning of the pore diameter in ZIF glass may enable liquid-processable ZIF glass membranes for challenging gas separations.

“…This method has shown promise in several studies, and it represents a significant step toward a more sustainable and eco-friendly Li production process. CO 2 is typically regarded as a waste product, but it could be transformed into a valuable asset for Li production, thereby contributing to a sustainable and circular economy [26][27]. In this context, it has become increasingly vital to explore and understand Li 2 CO 3 precipitation methods while also investigating innovative techniques that could potentially revolutionize the industry and result in a more sustainable and low-carbon society [28].…”

“…This can lead to additional refining steps that add to the process costs. Furthermore, the use of Na 2 CO 3 does not contribute to carbon capture or reduction strategies; therefore, exploring alternative methods, such as the use of CO 2 as a carbonate source for Li precipitation, would provide both economic and environmental advantages [26,27].…”

The market for lithium-ion batteries (LiBs) is growing rapidly, the demand for lithium (Li) in the form of lithium carbonate (Li2CO3), which is the most common lithium mineralization form, is therefore also increasing significantly. Li is conventionally extracted as Li2CO3 using sodium carbonate (Na2CO3) to precipitate Li ions in an aqueous Li solution. However, Na2CO3 can also be replaced by CO2, which highlights the potential of using CO2 as a sustainable and economically viable alternative. This review focuses on technologies that utilize CO2 for Li2CO2 precipitation. First, the use of CO2 gas and Na2CO3 as carbonate sources are compared, and the need to consider important operating conditions with CO2 bubbling are then presented. Attempts made to increase the specific surface area of the reaction surface to enhance the utilization of CO2 gas and to produce micro-sized Li2CO3 powders are then reported, and the limitations associated with CO2 gas utilization are discussed. Although CO2 precipitation has limitations in terms of efficiency, scalability, and the fine-tuning of reaction conditions, this review shows that if CO2 precipitation technology is further developed, its use could be key to extracting and recycling next-generation Li.

“…Aqueous formate (FM) solution can be used as a carbon carrier for geologic carbon storage. − FM (HCOO – ) is the simplest carboxylate and conjugate base of formic acid. Alkali FM salts such as sodium FM (HCOONa) and potassium FM (HCOOK) are highly soluble in water; for example, the solubility of potassium FM at 20 °C is 76 wt % .…”

This paper presents new data on core-scale wettability alteration of carbonate porous media with FM concentrations up to 30 wt % in NaCl brine. Experimental data from Amott tests, core floods, calcite dissolution experiments, and zeta potential measurements were analyzed to mechanistically understand the wettability alteration observed in the experiments. Static calcite dissolution tests showed that the degree of dissolution increased with increasing FM concentration in NaCl brine, even with an initially neutral pH. For example, the calcium concentration in the 30 wt % FM solution was 15.9 times greater than that in the NaCl brine with an initial pH of 7.0. Furthermore, reducing the initial solution pH from 7.0 to 6.1 for the 30 wt % FM solution caused the calcium ion concentration to increase by a factor of 3.2. Geochemical modeling and Raman analysis indicated that increased calcite dissolution was caused by interactions between calcium and FM ions. The 30 wt % FM solution with an initial pH of 6.1 yielded 4.7 times greater oil recovery than the NaCl brine in the spontaneous imbibition. The resulting Amott index indicated the wettability alteration to a water-wet state by the FM solution. The 30 wt % FM solution with an initial pH of 7.0 yielded only 30% greater oil recovery than the brine in the spontaneous imbibition; however, it reached nearly the same total oil recovery (spontaneous and forced) as the 30 wt % FM solution with an initial pH of 6.1. A numerical model was calibrated using core flood data, based on which the relative permeabilities indicated the core-scale wettability alteration by FM solutions. Results showed that increasing the FM concentration in the injection brine rendered the initially oil-wet core to a more water-wet state and that the in situ solution pH played an important role in wettability alteration by FM solution in carbonate media.
