Summary: The study explores the influence mechanism of hydroxyl groups on the adsorption of SO2 by activated carbon through experiments and simulations. The results show that hydroxyl functional groups promote the physical adsorption of SO2 on activated carbon by increasing its polarity. The hydroxyl groups also enhance the physisorption of SO2 and H2O through dipole-dipole interactions and hydrogen bonding. The coexistence of SO2, H2O, and O2 on activated carbon promotes their mutual physisorption through non-covalent interactions.

Summary: The reductive carbonization of cellulosic fibers using nano-sized nickel catalysts in the presence of hydrogen results in the production of activated carbon fibers with high adsorption capacities for volatile organic compounds. These reductive ACFs exhibit a unique surface chemistry and morphology, attributed to the activity of nanocatalysts, leading to enhanced benzene adsorption capacity. The highly conductive network structure of the ACFs allows for efficient material regeneration through electrothermal desorption, making them promising for industrial applications such as air quality control, gas separation, and fuel storage.

Summary: The presence of Per-and Polyfluoroalkyl Substances (PFAS) in water causes health effects on humans and animals. Adsorption methodology, specifically using classical powder activated carbon (AC) and Metal Organic Frameworks (MOFs), has shown effective performance in removing both short-chain and long-chain PFAS from water. However, the effectiveness and sorption mechanisms of these adsorbents have not been systematically investigated and compared due to the complexity of the adsorption process and the lack of standard experimental protocol. In this study, different adsorbents were synthesized and characterized, and a systematic isotherm adsorption protocol was performed to study the adsorption mechanisms and performance of these adsorbents for the removal of perfluorooctane sulfonic acid (PFOS) from water.

Summary: CO2 separation from CO2/CH4 and CO2/H2 mixtures is crucial for H2 production from biogas. Amine-functionalized carbon materials show promising CO2 adsorption performance, but the impact of amine edge positions needs clarification. In this study, the adsorption abilities of 19 graphene nanoflakes (GNFs) with two amines at different edge positions were evaluated. All structures exhibited superior CO2 adsorption compared to CH4 and H2. The CO2 adsorption in GNFs with isolated amines was influenced by charge transfer, while GNFs with adjacent amines showed stronger hydrogen bonding. The presence of methyl groups on the nitrogen hindered CO2 adsorption, and the interaction between amines and CO2 was affected by the presence of H2O.

Summary: Recently, there has been a lot of attention on semiconductor wastewater treatment due to environmental issues. Acid-resistant coatings are necessary for metal pre-filters used in this process. Perfluoroalkoxy alkane (PFA) is commonly used as an acid-resistant coating agent, but its superhydrophobicity hinders water permeability. To address this issue, a surface modification method using oxyfluorination was applied on the PFA-coated metal mesh. The treatment effectively converted the superhydrophobic surface to a hydrophobic one, improving the filtration performance of SiO2 microparticles in the PFA-coated stainless-steel mesh.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
