Study on a metal-organic complex [LaCu_6(μ-OH)_3(GlY)_6Im_6](ClO_4)_6 used for hydrogen storage

氢能是人类公认的未来的理想能源，而储氢材料是氢能应用的基础。金属-有机配合物作为一类新型的有发展前途的储氢材料正受到人们的重视。用P—C-T装置对金属-有机配合物[LaCu6（μ-OH）3（GlY）6Im6]（ClO4）6其进行了储氢性能测试。实验结果证明，在温度为299K，压力为0．1～3．2MPa的条件下，该配合物最大吸氢量达到0．41％，说明该配合物具有一定的储氢性能。最后结合该配合物晶体空间结构，初步分析其储氢机理为物理吸附。

Hydrogen energy is regard as the ideal energy in the future. Material for hydrogen storage is key step for the application of hydrogen energy. Metal-Organic Frameworks have been paid more and more attention as a new developmental hydrogen storage material by people. The hydrogen storage capacity of [LaCu6（μ-OH）3（GlY）6Im6]（ClO4）6 was studied by pressure-composition-isotherms （P-C-T） measurement, and its maximum capacity of hydrogen uptake is 0. 41% at 299K under the pressure from 0. 1-3.2MPa. The mechanism of hydrogen storage was deduced from the structure of the complex and ascribed to physical adsorbtion.
