摘要
金属有机骨架材料(MOFs)是一种新型的储氢材料,对氢气的吸附存储有较大的潜力。文中对MOF-5材料在低温至常温宽温区(77K~300K)范围内的吸氢性能展开理论研究。采用巨正则系综蒙特卡罗方法(GCMC)模拟不同温度和压力下氢气在MOF-5材料中的吸附等温线,并结合吸附位点来分析MOF-5材料在低温宽温区范围内的储氢性能,以及温度和压力对吸氢影响的原因。
Metal - Organic Frameworks are novel porous materials which have potential in hydrogen storage. But most previ- ous researches focus on specified situations like 77K, 298K or higher temperatures. Some theorical researches were done on the hydrogen storage performance of the Metal - Organic Framework - 5 in a wide temperature range from 77K to 300K in this study. The absorption isotherms of hydrogen in MOF - 5 at different temperatures and pressures were simulated by using Grand Canonical Monte Carlo (GCMC) method, combined with absorption sites. We concluded the temperatures and pressures" effect on hydrogen absorption performance.
