Summary: This study focuses on preparing an effective adsorbent for CO2 capture by modifying natural clay with amines. The results show that amine-modified clay can enhance CO2 adsorption capacity, but with lower capacities compared to untreated clay. The Langmuir model fits well with the experimental data, and thermodynamic parameters suggest that the process of CO2 adsorption on amine clay is physical, spontaneous, and exothermic.

Summary: In this study, a facile method to develop porous TiO2/BiOI adsorbent through a one-pot hydrothermal process and low-temperature calcination (280 degrees C) is reported. The porous TiO2/BiOI adsorbent achieves almost complete removal (99.4%) of tetracyclines, surpassing the removal efficiency of BiOI (20.2%) and TiO2 (71.1%). Furthermore, the TiO2/BiOI adsorbent can be easily regenerated through complete photodegradation and maintains above 98% of its adsorption capacity for 10 cycles, overcoming the limitations of other adsorbents/photocatalysts in terms of regeneration conditions, adsorption capacity, and recyclability.

Summary: Heteroatom-doped carbon materials have great potential in the electrochemical reduction reaction of CO2. This study reports a unique carbon precursor of soft template-containing porous poly(ionic liquid) that can be directly synthesized via free-radical self-polymerization. The carbonization process without any additive yields carbon materials with adjustable textural properties and N species. The integration of soft-template leads to the formation of hierarchical porous carbon material with a higher surface area and larger pore size. The champion catalyst exhibits high Faraday efficiency and current density in the CO2RR to CO reaction, which is attributed to the abundant graphite N species and hierarchical pore structure.

Summary: According to the requirements of sustainable green development, the efficient green synthesis of fluorine chemical products is an inevitable trend. In this study, ionic liquids were used as an effective catalyst in the dimerization reaction of hexafluoropropylene for the first time. The effects of different ionic liquids on the catalytic performance were systematically studied. The results showed that the most active catalyst was the trisubstituted thiocyanate imidazole ionic liquid [C(6)mmim][SCN], which had a high turnover frequency (TOF) of 108.36 h(-1) and a selectivity of 97.96%. Compared to traditional metal salt catalysts, the catalytic activity of ionic liquids was twice as high.

Summary: In this study, we demonstrate that ionic polyamide stabilized Ru nanoparticles act as a highly effective catalyst for the reductive amination of carbonyl compounds, providing high yield, large turnover frequency, stable recycling performance, and compatibility with a wide range of primary amines. The ionic polyamide support allows for easy adjustment of the surface chemical state and dispersion, leading to the formation of metallic Ru-0 species with high dispersion and suitable hydrogenation ability. The presence of ionic moieties is crucial for stabilizing the Ru species and enabling stable recyclability.
