摘要:

金属有机骨架(MOFs)作为一类新型多孔材料,因其独特和可调的孔道结构、高比表面积和高孔隙率等优点,近年来在中低温吸附式制冷和吸附储热领域得到了广泛的研究与关注。从MOFs对换热工质的吸附容量、系统热效率和稳定性等角度对比分析了不同MOFs材料在吸附式热转换领域的应用现状以及进一步提升材料性能的方法,通过分析可以发现MOFs材料的改性以及与其他材料的复合是提升吸附储热性能的有效方法,也是未来新型MOFs材料开发的一个重要方向,同时吸附热转换系统与MOFs储热材料的高效匹配性也是未来MOFs储热材料实用化的一个重要指标。

Abstract:

As a new kind of porous materials,metal-organic frameworks(MOFs) have received extensive research and attention in the field of medium and low temperature adsorption refrigeration and adsorption heat storage in recent years due to their unique and adjustable pore structure,high specific surface area and high porosity.The application status of different MOFs materials in the field of adsorption heat conversion and the methods to further improve the performance of the materials from the perspectives of the adsorption capacity of MOFs to the heat transfer medium,the thermal efficiency and stability were compared and analyzed.Through the analysis,it could be found that the modification of MOFs materials and the composite with other materials were effective methods to improve the adsorption thermal storage performance,and it was also a signifiacnt direction for the development of novel MOFs materials in the future.At the same time,the efficient matching between the adsorption heat conversion system and MOFs heat storage materials was also a crucial index for the practicality of MOFs heat storage materials in the future.

Key words: MOFs, adsorption property, adsorption heat conversion, thermodynamic cycle
