Abstract

The incorporation of Sn was attempted in-between the layers of Na-montmorillonite through the hydrolysis of (NH4)2SnCl6 in an aqueous environment under reflux. Intercalation was successful and the resulting structure was characterized by X-ray fluorescence (XRF) spectroscopy, X-ray diffractometry (XRD), surface area (BET) and thermogravimetric measurements, infrared (IR), 119Sn Mössbauer and multinuclear (27Al, 29Si and 119Sn) magic angle spinning (MAS) spectroscopies. It was found that the intercalated species was partially hydrated SnO2 which was kept between the layer with secondary forces: hydrogen bonds and van der Waals interactions. Upon heat treatment gradual and eventually complete dehydration of the intercalated species occurred and the bare SnO2 moved to the outer surface of the clay
