Summary: Researchers prepared metal-free 2D/2D C3N5/GO nanosheets and customized a type-II heterojunction based on band bending theory to enhance uranium extraction capacity. The structure of C3N5 was explained through electron energy loss spectroscopy and synchrotron-based X-ray absorption fine structure, showing a expanded light response range compared to C3N4. Density functional theory was used to demonstrate the presence of alternating energy levels for continuous injection of photogenerated electrons into the surface of GO, resulting in effective electron-hole pair separation and increased material activity. The 2D/2D C3N5/GO heterojunction achieved a high uranium removal ratio of 96.1% even at low concentration and 93.4% after gamma-ray exposure, laying a foundation for future customization of nonmetal-based 2D/2D nanohybrids for uranium-containing wastewater enrichment.

Summary: In this study, the adsorption and desorption processes of CO on Pt(111) surface are investigated using density functional theory calculations combined with Monte Carlo simulations. The results show that the average adsorption energy determines the adsorption process, while the low energy part of the adsorbate stability distribution describes the desorption process.

Summary: The chemical industry contributes around 7% of the global GDP, with 40% of its energy consumption coming from separation/purification processes of commodity chemicals. The use of recyclable adsorbents, such as metal-organic framework (MOF) physisorbents, shows promise in reducing this energy footprint, particularly in the separation of C6 cyclic hydrocarbons like benzene and cyclohexane. Despite the potential of MOFs as selective adsorbents, further research is needed to fully explore their capabilities in this niche area.

Summary: Waste polymer materials have the potential to be recycled or enhanced for environmental applications. Hypercrosslinked polymers (HCPs) are a good option for recycling polymers. In this study, waste-expanded polystyrene and waste polycarbonate were used as precursors to create HCPs adsorbents for O2/N2 adsorption. Characterization analysis was conducted to determine the morphology and structure of the adsorbents. The fine adsorbent, waste-expanded polystyrene, showed the highest adsorption for O2 and N2, with 12.78 and 7.67 (mmol/g) respectively, at 5 degrees C and 10 bar. The results suggest that the method described in this study is a promising approach for eco-friendly air separation and purification.

Summary: In this work, an oxygen separation system based on an oxygen-selective sorbent, YBaCo4O7+delta (YBC114), was designed, built, and evaluated. The system can provide an inert sweep gas with low oxygen partial pressure for various applications. The study comprehensively investigated the oxygen separation performance of YBC114 and determined its optimal sorption and desorption temperatures. Despite some challenges, the study demonstrates the potential of using the oxygen-selective sorbent for inert gas production and guides the development of new sorbent materials to make this application economically feasible.

Summary: In this study, the elasticity of different single-layer tetrabenzoporphyrin (H2-TBPor) and phthalocyanine (H2-Pc) based 2D COFs was numerically investigated using a density-functional based tight-binding approach. By calculating the 2D bulk modulus and equivalent spring constants of the molecular building blocks, the researchers were able to predict the 2D bulk modulus based on the properties of the isolated molecules, offering a pathway to optimize the elastic properties of 2D COFs.
