Synthesis and Characterization of Polycyclic Aromatic Hydrocarbons in GaPO4-LTA Single Crystals

Abstract

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.

Key words: GaPO₄-LTA, Pyrolysis, Polycyclic aromatic hydrocarbons(PAHs), Fullerenes
