The separation of methane from natural gas poses a significant and crucial challenge in the industry. Currently, capture CH4 is dominated by distillation, which an energy consuming process. Here, we present CALF-20, metal–organic framework with three-dimensional pore structure, for separating C2H6/CH4 CH4/N2 mixtures. Interestingly, CALF-20 shows satisfactory uptake 1.11 mmol/g selectivity 22.7 (298 K, 100 kPa). on at 0.5 kPa reaches 15.0. In addition, breakthrough experiments demonstrated that could effectively separate Molecular simulations highlight role strong C–H···N C–H···π interactions between adsorbates achieving highly selective exhibits superior persistent reusability, outstanding water moisture stability, low ligand cost ($53/kg).

Abstract Natural gas, primarily composed of methane (CH 4 ), represent an excellent choice for a potentially sustainable renewable energy transition. However, the process compressing and liquefying CH transport storage typically results in significant losses. In addition, order to optimize its efficacy as fuel, content natural gas needs be increased level at least 97 % ensure quality efficiency various applications. Metal‐organic frameworks (MOFs) novel category porous materials that possess exceptional capability modifying pore size chemical environment, making them ideally suited adsorption propane (C 3 H 8 ethane 2 6 carbon dioxide (CO nitrogen (N hydrogen sulfide (H S) facilitate purification from gas. this paper, we systematically summarize mechanism by which MOF leveraging structural characteristics inherent materials. The focus further research should also directed towards investigation flexible MOFs, resolution trade‐off dilemma, commercial application MOFs.

The recycling of low-concentration coal-bed methane (CBM) is environmentally beneficial and plays a crucial role in optimizing the energy mix. In this work, we present strategy involving pore chemical modification to synthesize series bimetallic diamond coordination networks, namely CuIn(ina)4, CuIn(3-ain)4, CuIn(3-Fina)4 (where ina = isonicotinic acid, 3-ain 3-amino-isonicotinic 3-Fina 3-fluoroisonicotinic acid). Among these, amino-functionalized CuIn(3-ain)4 exhibits excellent CH4 adsorption capacity (1.71 mmol g–1) CH4/N2 selectivity (7.5) due its optimal size environment, establishing it as new benchmark material for CBM separation. Dynamic breakthrough experiments confirm exceptional separation performance CuIn(3-ain)4. Notably, demonstrates stability under wet conditions maintains outstanding even high-humidity environments. Additionally, theoretical simulations provide valuable insights into how selective can be fine-tuned by manipulating geometry. Regeneration tests cycling evaluations further underscore remarkable potential highly efficient adsorbent CBM.

Abstract Purifying methane (CH 4 ) from natural gas and coal mine (CMM) is of great significance but challenging in the chemical industry. Herein, a robust ultramicroporous metal‐organic framework (MOF) reported, which can be synthesized on gram scale by stirring under room temperature. Single‐component adsorption isotherms gases , ethane (C 2 H 6 ), propane 3 8 nitrogen (N )) breakthrough experiments indicate that MOF separate CH efficiently /C ternary mixture, with super high purity‐CH production 154.7 cm g −1 . Additionally, shows higher capacity than N resulting excellent separation performance for /N mixture. Notably, binding sites precisely determined single‐crystal X‐ray data, further confirmed molecular simulation. It found there are multiple hydrogen bonds C─H···π interactions between framework. This work offers an candidate material purification both efficiency.
