SYNTHESIS AND HYDROGEN STORAGE CHARACTERISTICS OF ORGANIC-INORGANIC HYBIRD MATERIALS Cu3 （BTC） 2

探索了有机-无机杂化配位聚合物Cu3（BTC）2的水热合成。适宜的合成Cu3（BTC）2的条件是373K、晶化3d、Cu（NO3）2和H。BTC的摩尔比0．6～3．0、醇和水的摩尔比0．440～0．146。初步考察了Cu3（BTC）2的储氢特性。结果表明，Cu3（BTC）z在77K、压力为1．41MPa时，储氢量可达到2．10％（质量分数），比典型的硅铝沸石NaX高约0．50％，是一种值得关注的储氢材料。

Hydrothermal synthesis method of an organic-inorganic hybrid coordination polymer, Cu3 （BTC）2, was explored. The feasible synthesis conditions for Cu3 （BTC）2 were the copper nitrate/trimesic acid molar ratio of 0.6-3.0, the ethanol/water molar ratio of 0. 440-0. 146, 373 K and crystallization time of 3 d. The hydrogen storage properties of Cu3 （BTC）2 were studied. It is proved that the hydrogen storage of Cu3 （BTC）2 could be 2.10%（mass fraction） at 77 K in the pressure of 1. 41 MPa , which was 0. 50M more than that of typical aluminosilicate zeolites, being a kind of hydrogen adsorption materials of great worth.
