A Study of the Encapsulation of Nickel Phthalocyanine in Molecular Sieve Zeolites of the FAU Type

摘要

Nickel(II) phthalocyaninate spectroscopy (NiPc) was synthesized in the supercages of zeolite FAU by the template synthesis method at two different temperatures of 200 and 300 deg C and characterized by diffuse reflectance spectroscopy,UV-Vis spectroscopy,X-ray powder diffraction,and IR.The results show that the catalyst synthesized at 200 deg C contains a higher amount of complex as monomeric species encapsulated in the supercages.At elevated temperature,higher amount of the NiPc may be hosted in the mesopores and/or on the external surface of the zeolite as aggregates.
