Abstract

Mordenite zeolite was synthesized without organic structure directing agents. We used ion exchangeto create the zinc sulphide nano-clusters inside the zeolite framework. The as-synthesised Na-MORzeolite and exchanged samples Zn-MOR, ZnS-MOR zeolites were characterised by X-ray powderdiffraction XRPD , solid state magic angle spinning nuclear magnetic resonance MAS NMR ,energy-dispersive X-ray EDX elemental analysis, Brunauer-Emmett-Teller BET surface areaanalysis, and transmission electron microscopy TEM . PXRD shows that exchange does not affectthe zeolite framework, a a slight increase in the unit cell parameters from Na-MOR to ZnS-MOR isobserved. The successful incorporation of Zn2+into the MOR framework is confirmed by 23Na NMR.EDX, BET, and TEM analyses also provide evidences for the formation of ZnS nano-clusters
