Preparation and immobilization of diNOsarcobalt(III) complex in zeolite y for the catalyzed production of hydrogen peroxide

Abstract

Recebido em 6/2/13; aceito em 15/5/13; publicado na web em 17/7/13, (diNOsar = 1,6,10,13,16,]eicosane), was synthesized and immobilized in the cavities of a Y zeolite by the reaction of precursor species in the pores of the zeolite. The encapsulated material was compared to the compound diNOsarcobalt(III) chloride, [Co(diNOsar)]Cl 3 . Both diNOsarcobalt(III) chloride and the zeolite-encapsulated complex, [Co(diNOsar)] 3+ /zeolite, were obtained in high yield and characterized by ultravioletvisible and infrared spectroscopy. X-ray diffraction demonstrated the incorporation of the complex cation into the pores of the zeolite. The catalytic production of hydrogen peroxide from oxygenated water confirmed the successful synthesis of the complex diNOsarcobalt(III) immobilized in the zeolite.
