【摘要】 沸石分子筛是一种笼型孔洞骨架晶体,脱水后空间十分丰富,具有很大的内表面积,可以吸附相当数量的吸附质。A型、X型分子筛具有不同的孔笼结构和组成,采用P-C-T储氢装置研究了它们在低温(77 K)下的储氢性能,结果表明:沸石分子筛储氢性能受骨架结构、孔容积、孔径大小的影响很大,阳离子的不同也会引起分子筛储氢性能的变化,其中A型分子筛孔口较小影响尤为显著。更多还原

【Abstract】 Zeolites as media for hydrogen storage was based on its abundant of cavities. They encompass rage of different pore geometries and composition. We have investigated the use of zeolites A and X as hydrogen storage materials at 77 K at P-C-T setup. The results showed that the hydrogen uptake in zeolites is dependent upon framework, the size of cavities. In zeolites,a pore blocking by large cations is a major factor restricting hydrogen uptake.更多还原
