利用水热合成方法,以自组装的铜胺配合物为模板剂,合成出具有AWO分子筛结构的磷酸铝微孔化合物[Cu(en)2]0.5[Al3P3O12(OH)],命名为AlPO-CJ53.单晶结构解析表明,其结晶在单斜晶系P21/n(No.14)空间群,晶胞参数为:a=0.85547(11)nm,b=1.7671(2)nm,c=0.90500(12)nm,β=107.725(2)°,V=1.3031(3)nm3.AlPO-CJ53的三维骨架结构是由AlO4(OH)/AlO4与PO4交替连接形成,含有沿着c方向的一维八元环孔道.自组装的铜胺配合物离子Cu(en)22+平衡骨架负电荷,存在于八元环孔道中.AlPO-CJ53经400℃煅烧后其晶体结构转变为具有ATV分子筛结构的AlPO4-25.
The aluminum phosphate microporous compound [Cu (en) 2] 0.5 [Al3P3O12 (OH)] with AWO molecular sieve structure was synthesized by the hydrothermal method and the self-assembled copper amine complex as templating agent. AlPO-CJ53 The crystal structure analysis of the single crystal shows that the crystal lattice in the monoclinic space group P21 / n (No.14) is a = 0.85547 (11) nm, b = 1.7671 (2) nm and c = 0.90500 12) nm, β = 107.725 (2) °, V = 1.3031 (3) nm3.A three-dimensional framework structure of AlPO-CJ53 is formed by the alternating connection of AlO4 (OH) / AlO4 and PO4, The pore structure of the ring is characterized by the presence of Cu (en) 22+, which is the anion of the self-assembled copper-amine complex Cu (en) 22+ and exists in the octametafluorocyclohexane channel.After calcination at 400 ℃, the crystal structure of AlPO-CJ53 is changed to AlPO4 -25.
