Clays have demonstrated an important role in many industrial processes and its modification have been a promising line of research, such as its intercalation and pillaring. The synthesis of vermiculite modified with aluminum and aluminum-lanthanum has great relevance, since the materials obtained can be used in separation processes by adsorption and catalysis. For characterization of the crystallographic phases of the synthesized materials were obtained diffraction patterns (XRD) that confirmed the effectiveness of the methodology used, and to evaluate the morphology were carried out nitrogen adsorption analysis (BET), where the results confirmed the mesoporosity of the synthesized materials. 27Al MAS NMR spectrometry was applied to distinguish between tetrahedrally coordinated aluminum and octahedrally coordinated.
