摘　　要：金属有机框架材料(Metal-organic frameworks,MOFs)因其优异的孔道特性和灵活的结构可调性,作为新型吸附材料受到气体分离和存储领域的广泛关注。然而,在天然气的纯化和存储领域的使用需要对MOFs固体吸附剂进行系统的设计,简要论述了MOFs在天然气纯化过程中对二氧化碳和硫化氢两大杂质的分离,以期提高天然气的纯度,为高效的存储奠定基础,接下来,从吸附和解吸两个角度出发,论述利用MOFs进行天然气存储的考量因素。最后,总结了在天然气纯化和存储领域MOFs的设计合成思路以及MOFs吸附剂在稳定性、多功能性等方面所面临的挑战,以此提高MOFs吸附剂在未来推广使用的可能性。Metal⁃organic frameworks(MOFs)have received wide attention as new adsorbent materials for gas separation and storage due to their excellent pore characteristics and flexible structure adjustability.However,MOFs solid adsorbents need to be systematically design in the field of natural gas purification and storage.The separation of carbon dioxide and hy⁃drogen sulfide in natural gas purification process was briefly reviewed,which would improve the purity of gas and lay a foun⁃dation for efficient storage.Then,the consideration of using MOFs for natural gas storage from two angles of adsorption and desorption was discussed.Finally,the thought of MOFs design and synthesis and the challenge of stability and versatility in the field of natural gas purification and storage were summarized to improve the possibility of MOFs adsorbents'wide use in the future.
