Heterostructured Nanohybrid of Zinc Oxide-Montmorillonite Clay
According to X-ray diffraction, N2 adsorption−desorption isotherm, and field emission-scanning electron microscopic analyses, it was found that the intercalation of zinc oxide nanoparticles expands the basal spacing of the host montmorillonite clay, and the crystallites of the nanohybrids are assembled to form a house-of-cards structure.

(Eg) value of 3.37 eV [12]. The Ag@ZnO-saponite nanocomposite presents a major con-tribution at 3.15 eV and a minor contribution at 2.22 eV. The shift in the band gap value suggests the influence of ZnO confinement in the clay mineral matrix. Probably the opti-cal gap at 3.15 corresponds to ZnO and the presence of Ag NPs corresponds to the optical
