Evaluation of metal–organic frameworks (MOFs) for adsorbed natural gas (ANG) technology employs pure methane as a surrogate (NG). This approximation is problematic, it ignores the impact other heavier hydrocarbons present in NG, such ethane and propane, which generally have more favorable adsorption interactions with MOFs compared to methane. Herein, using quantitative Raman spectroscopic analysis Monte Carlo calculations, we demonstrate selectivity high-performing MOFs, MOF-5, MOF-177, SNU-70, mixture (95:5) that mimics composition NG. The on storage deliverable capacities these adsorbents during successive cycles desorption, simulating filling emptying an ANG tank, also demonstrated. study reveals gradual reduction performance particularly smaller pore volumes, due accumulation over long-term cycling, until steady state reached substantially degraded performance.

The carbon dioxide (CO2) capture and utilization strategy has emerged as an innovative multifaceted approach to counteract emissions. In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; H3TATB = 4,4',4″-s-triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites basic nitrogen-rich triazines. BaTATB demonstrated selective CO2 adsorption high heat of adsorption. Its abundance (Ba clusters) (triazine) makes ideal catalyst for the cycloaddition epoxides in two- three-component reactions. Furthermore, is exceptional recyclable aromatic amines, enabling high-yield synthesis cyclic carbonates oxazolidinone at 1 bar under moderate, solvent-free, cocatalyst-free conditions. Additionally, recycled nine seven consecutive cycles carbonate no substantial decrease catalytic activity. Using density functional theory, we rational design metal-organic frameworks that exhibit excellent conversion.

Abstract The long‐term development of fossil energy has led to the destruction carbon balance. Carbon capture technology needs be used reduce emissions before clean completely replaces energy. Metal‐organic frameworks (MOFs), a porous crystalline material, show great potential in gas adsorption and attracted attention. predictability MOFs' structure function also make it possible use computational methods advance accelerate research. This review gives brief overview dioxide separation by MOFs, including membrane separation. In future, is expected crucial area research for applications due its favorable characteristics such as high treatment efficiency low footprint, while mixed matrix membranes (MMMs) have been given more attention scholars their lower cost better performance. summary, developing high‐performance MOFs or MOF derivatives researching efficient methods, application MOF‐based MMMs, should focus future this field.

Abstract Efficient photocatalytic CO 2 reduction coupled with the photosynthesis of pure H O is a challenging and significant task. Herein, using classical photoreduction site iron porphyrinate as linker, Ag(I) clusters were spatially separated evenly distributed within new metal–organic framework (MOF), namely Ag 27 TPyP‐Fe . With water electron donors, exhibited remarkable performances in artificial photosynthetic overall reaction yield 36.5 μmol g −1 h ca 100 % selectivity, well evolution rate 35.9 Since liquid phase can be more readily from gaseous products photoreduction, high‐purity concentration up to 0.1 mM was obtained. Confirmed by theoretical calculations established energy level diagram, reductive iron(II) porphyrinates oxidative an integrated functioned synergistically achieve photosynthesis. Furthermore, photoluminescence spectroscopy photoelectrochemical measurements revealed that robust connection ligands facilitated efficient charge separation rapid transfer, thereby enhancing activity.
