Summary: A new approach for polymer functionalization of ordered mesoporous silicas (OMS) was demonstrated by cocondensation of silica precursor and a functional polymer, using a tailored amphiphilic copolymer as pore template. The novel strategy allows for incorporation of the functional polymer into the mesoporous silica, resulting in materials with high specific surface area and large pores, and acceptable CO2 adsorption capacity with selectivity towards CH4 and N2.

Summary: In this study, aminosilane-modified MCM-41 and SBA-15 mesoporous silicas were synthesized using sodium silicate extracted from gold mine tailings slurry. The CO2 adsorption capacities of these synthesized samples were found to increase with higher amine contents and specific surface area, with the aminosilane-modified MCM-41 and SBA-15 showing the highest adsorption capacities. The Avrami model was able to accurately represent the adsorption kinetic data for all adsorbents, indicating a multiple reaction pathway occurring in CO2 adsorption, and the aminosilane-modified samples exhibited good regenerability after multiple adsorption-desorption cycles.

Summary: Studies were conducted to investigate the adsorption of Cs+ and Sr2+ ions on mesoporous silicas with different pore size distributions. The results showed that the adsorption of Sr2+ was not significantly affected by the pore size, while that of Cs+ was higher for silicas with larger fractions of micropores. X-ray absorption fine structure analysis revealed that both ions formed outer-sphere complexes with the mesoporous silicas. Adsorption experiments were analyzed using a surface complexation model and it was found that the equilibrium constant for the adsorption of Sr2+ was constant regardless of the pore size, whereas that of Cs+ increased with decreasing pore size.

However, the oxidation of phosphorene layers in ambient conditions affects its performance. This study used first-principles calculations to investigate the interaction of phosphorene with oxygen and water molecules. The results show unfavorable energetics for hydroxilated and hydrogenated phosphorene layers, as well as increased water adsorption on oxidized layers.

Summary: Metal-Organic Frameworks (MOFs) with open metal sites (OMS) can strongly interact with polar gases/vapors. However, their selective adsorption is usually hindered by a high affinity to water under ambient conditions. This study challenges the paradigm by demonstrating that metal(III) polycarboxylates MOFs, such as MIL-100(Fe), with a high concentration of OMS, enable the selective capture of polar VOCs even in the presence of water. The adsorption mechanism involves a direct coordination of the VOC on the OMS, which has a stronger interaction energy compared to water.

Summary: In the face of global warming and the energy crisis, it is crucial to reduce the emissions of greenhouse gases like CO2 and CH4 and recycle biomethane from landfill biogas. This study demonstrates the potential of converting glycerol, a by-product of biodiesel production, into activated carbon using potassium acetate as an activating agent. The activated carbon exhibits high adsorption capacities for CO2 and CH4, with selectivity values that enable effective separation. Additionally, the study finds that the CO2 emissions produced during activated carbon synthesis can be easily neutralized through their use in small biogas production units.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
