To overcome this disadvantage, in the present work,we synthesized a novel NZVI/NaY catalyst by a simple and effective ion exchange and insitu reduction method. NaY zeolite was chosen as the support due to its unique properties, which could give it advantages over other carriers (such as clay, laponite, bentonite, etc.). Zeolites are crystalline aluminosilicates
made up of corner-sharing SiO4 4− and AlO4 5− tetrahedra and the framework contains a large number of pores, channels and cages of various dimensions that can accommodate organic molecules of right size. They are proven ion exchange materials where the indigenous (typically sodium) charge balancing cations are readily exchanged with metal cations in solution. In the various types of zeolites (Si/Al ratio increased in the order AbXbYbZSM), zeolites with a low Si/Al ratio
