Encapsulation of Cu(II) Purine Derivative Complexes in NaY Zeolite

The encapsulation of Cu(II) purine derivative complex was carried out by ion exchange of the complex from aqueous solutions into zeolite NaY. The entrapped complex was characterized by spectroscopic methods (FTIR and ICP-AES) and surface analysis (XRD). The various techniques of characterization used show that the Cu(II) complex was effectively encapsulated in the zeolite and this process does not modify the morphology and structure of the NaY zeolite. These materials have potential applications in heterogeneous catalysis in mild reaction conditions.
