摘要: Abstract Defect-free highly siliceous zeolites were prepared by dealumination of zeolite Y using silicon tetrachloride. Tris(bipyridyl) ruthenium (II) complex, [Ru(bpy) 3 ] 2+ , was synthesized inside the supercages faujasitic neutral Ru(bpy)Cl as starting material. The conventional procedure ion-exchange hexammine could not be used because lack sites in zeolites. emission quenching intrazeolitic Ru(bpy) oxygen dissolved water studied. Dealumination zeolitic framework leads to a hydrophobic environment that promotes transfer from zeolite. Transparent zeolite-dispersed siloxane films and examined sensors for oxygen.
