摘　　要：采用溶剂热方法合成了沸石咪唑酯骨架结构材料Co-ZIF-9,并将其用于非均相催化氨硼烷水解放氢实验.结果表明:配位的Co-ZIF-9在室温下能够有效地催化氨硼烷放出氢气,且其催化活性远高于Co纳米粒子,Co-ZIF-9的多孔结构在催化中起了很大的作用.另外,Co-ZIF-9催化水解氨硼烷的活化能约为40.8 k J mol-1,低于多数用于该催化实验的其他催化剂,表明所合成的沸石咪唑酯骨架结构材料Co-ZIF-9具有优越的催化性能.Crystalline zeolite imidazolate framework ZIF-9 has been prepared via solvothermal method,and used as an efficient heterogeneous catalyst for the hydrolytic dehydrogenation of ammonia borane（ AB） complex to generate a stoichiometric of hydrogen at room temperature. CoZIF-9 exhibited much higher catalytic activity than the bare Co nanoparticles（ NPs） for hydrogen generation from the hydrolysis of AB,duo to that the porous structure of Co-ZIF-9 play an important role in the catalytic hydrolysis of AB. Additionally,the activation energy for Co-ZIF-9 was measured to be approximately of 40. 8 k J·mol^-1,being lower than most of reported activation energy values for the same reaction using many different catalysts,indicating the superior catalytic performance of Co-ZIF-9.
