Summary: In this review, the successful fabrication of 2D amorphous materials using supercritical carbon dioxide (SC CO2)-assisted chemical and material processing is discussed, although the amorphization mechanism in SC CO2 is complex. Different types of 2D amorphous materials prepared with SC CO2 are introduced, along with the possible amorphization mechanism and their impact on the structures and properties of 2D materials. Applications of these materials are presented and future development prospects for SC CO2-assisted fabrication of 2D amorphous materials are discussed. The study of SC CO2 induced amorphization not only provides theoretical understanding of the process, but also guides the preparation and application of 2D amorphous materials with specific structure and property, indicating the promising future of SC CO2-assisted process in material design and engineering.

Summary: This study demonstrates the synthesis of TiO2 nanoparticles with enhanced optical properties in supercritical medium for the fabrication of light-responsive photoanodes. The photoelectrochemical CO2 reduction tests show improved reaction performance under UV irradiation, resulting in higher selectivity and photocurrent densities for ethylene and methanol. Additionally, the maximum solar-to-fuels values achieved using these TiO2-based materials are significantly higher than those observed with other photoanodes. Therefore, this research highlights the benefits of using TiO2 materials synthesized in supercritical medium for efficient photoelectroreduction of CO2 into valuable products.

Summary: In this study, a one-pot synthesis of valuable glycerol carbonate (GC) from CO2, glycerol (Gly), and styrene oxide (SO) was successfully achieved using easily prepared protic ionic liquids (ILs) under atmospheric pressure. The high catalytic activity of 1,8-diazabicyclo[5.4.0]undec-7-enenium iodide (HDBUI) was attributed to the strong nucleophilicity and substrate activation provided by the synergistic effect of the protic HDBU+ cation and I- anion. High GC yields were also obtained when simulated flue gas and crude Gly were used as substrates.

Summary: This study focuses on the pretreatment of residual lignocellulosic biomass using the alkaline solvent-imidazole to obtain cellulose- and hemicellulose-rich fractions while depolymerizing lignin. The highest cellulose content was achieved at 160 degrees C for 4 hours, with a delignification yield of 65.2 +/- 0.4 wt%. The efficiency of enzymatic digestibility was also analyzed, showing a linear relationship between delignification yield and glucan to glucose yield. Antioxidant activity and total phenolic content of recovered imidazole were determined, with the presence of added-value phenolic compounds identified through HPLC-MS analysis.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
