Covalent organic framework materials with advanced topologies for efficient methane adsorption

<正>Methane, as the main component of natural gas, is a key transitional fuel resource due to its abundance and relatively low carbon emissions, aligning with global carbon neutrality objectives [1]. Traditional natural gas storage methods, such as liquefied and compressed natural gas, require costly infrastructure and high-pressure conditions. Alternatively, adsorbed natural gas offers a safer, more cost-effective, and environmentally friendly solution by enhancing storage capacity at reduced pressures through the use of methane adsorbents [2].
