Abstract: The phthalic anhydride-urea route was employed to in-situ synthesize CoPc in the supercages of zeolite Y. The prepared CoPcY was characterized by various physicochemical methods and catalytic reaction. The results show that the route is a simple and effective method for in-situ synthesis of CoPc complexes in the supercages of zeolite Y. In the route, the synthesis parameters (synthesis temperature, catalyst and salt used in ion exchange) have great influence on the properties of the prepared CoPcY, in which the optimum synthesis temperature for CoPc is 180℃ and a suitable salt for ion exchange is cobalt chloride. The CoPc in-situ synthesized in supercages of Zeolite Y by this route shows high catalytic activity for cyclohexane oxidation under mild reaction conditions, and TON is over 5 000 as H2O2 is used as oxidant, reaction temperature is 60 ℃ and reaction time is 10 h.
