| 摘 要： | 以γ-甲基吡啶(mPy)为模板剂合成了具有A型分子筛骨架结构的磷酸镓(GaPO4-LTA)单晶,并研究了mPy在GaPO4-LTA超笼内的高温热解反应.mPy在GaPO4-LTA笼中热解后形成稠环芳烃类物质PAHs(Polycyclicaromatichydrocarbons).这些PAHs物质的种类与升温速度和终止温度密切相关.在GaPO4-LTA笼中生成的PAHs可望成为合成富勒烯的前驱体.

| Abstract: | Perfect gallophosphate GaPO4-LTA single crystals, with the LTA framework structure, were synthesized by using 4-methly pyridine(mPy) as the structure-directing template. And the pyrolysis of mPy was studied in the α-supercage of GaPO4-LTA in vaccum or under a nitrogen flow. Under these conditions, PAHs(polycyclic aromatic hydrocarbons) were produced in the α-cages. The kinds of the species of PAHs formed are closely related to the rate of temperature increase and the terminated temperature. The PAHs formed in the cages of GaPO4-LTA may act as a precursor for the formation of small fullerene molecules by further rearrangement in the inorganic host. |
