Summary: Nanoporous carbon sorbents modified with oligomers of lactic and glycolic acids were synthesized without the use of catalysts and organic solvents. The modification of carbon sorbents with oligomers of hydroxy acids resulted in deterioration of textural characteristics and an increase in the oxygen content. The modified sorbents exhibited higher hydrophilicity and adsorption capacity compared to the unmodified sorbent. Furthermore, the modified carbon sorbents showed different biological activities against various pathogenic bacteria and fungi compared to the initial sample.

Summary: CO2 chemisorption via C-O bond formation is an efficient method in carbon capture, especially using phenolate-based ionic liquids as sorbents to produce carbonate products. The study utilized alkali metal cations coordinated with crown ethers to construct phenolate-based systems, avoiding the involvement of active protons in CO2 chemisorption. The CO2 uptake capacity and reaction enthalpy were significantly influenced by coordination effect, alkali metal types, and alkyl groups on the benzene ring.

Summary: Per- and polyfluoroalkyl substances (PFASs) are highly persistent chemicals with significant global environmental challenges. A study comparing the removal performance of granular activated carbon (GAC) and ion exchange resin (IX) for PFASs found that the length of PFAS chains and functional groups determine the mass transfer zone (MTZ) height and optimal empty bed contact times (EBCTs). Cost sensitivity analysis showed that IX was the most cost-effective adsorbent for removing both long and short chain PFASs compared to GAC.

Summary: The study revealed that Pd/Au(111) has a Delta G close to 0 kJ/mol when the coverage of adsorbed hydrogen is near 1 ML, while Pt/Au(111) shows a similar Delta G under a wide range of hydrogen coverage conditions from 1 to 3 ML. The catalytic sites for Pd nanoislands are located at the edges, while for Pt nanoislands, they are distributed on both the steps and terraces.

Summary: Density functional theory calculations were used to study the sequential adsorption of hydrogen on Pd and Pt atomic site catalysts on Au(111). It was found that Pd systems have near-zero free energy of hydrogen adsorption (∆GHads≈0) under various coverage conditions of adsorbed hydrogen, while Pt systems only exhibit such behavior at high coverage conditions. This difference is due to the preference of hydrogen for high-coordination and low-coordination sites on Pd and Pt, respectively. The low coordination of hydrogen in Pt/Au results in multiple adsorption sites with near-zero ∆GHads in SCC. These findings contribute to the understanding of the distinct catalytic properties of Pd/Au and Pt/Au.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
