ZSM-5 zeolite synthesis in the presence of a copper-phthalocyanine complex characterization by ESR and 129Xe NMR.

In the presence of a copper phthalocyanine complex (CuPc), it is possible to synthesize ZSM-5 zeolite containing the complex, and the crystallinity is good, provided that the amount of CuPc trapped is lower than the number of channel intersections where it can be located without too much distortion. The crystallinity is retained after decomposition of the CuPc in a stream of air at 500 degrees C. The copper-ZSM-5 system is characterized by the combined application of xenon adsorption, ESR and 129Xe NMR spectroscopy.
