| Abstract: |
| Clay intercalated metal oxide nanocomposites are an important practical materials in various fields. Such metal oxide grafted inorganic layered materials can represent a very high efficiency and sensitivity for removing pollutants from water body, anticorrosive behavior, catalytic properties etc., which are highly important for environmental aspects. In this work, we report a simple and high efficient ultrasound assisted method for the encapsulation of MO2 nanoparticles (M= Ce and Zr) into a pillared organoclay to yield a multilayer MO2(M=Ce, Zr)/organoclay nanocomposite. The synthesis reaction proceeded by preparation of metal oxide precursors and their intercalation into pillared clay galleries using ultrasound waves with the power of 240 W for 2h. The products were characterized by several techniques including X-Ray Diffraction (XRD), Inductively Coupled Plasma Spectrometry (ICP), Energy Dispersive Spectroscopic (EDS) and Scanning Electron Microscopy (SEM). Low-angle X-Ray Diffraction (LXRD) patterns clearly indicated a noticeable expansion of interlayer spacing of clay layers for the prepared product in comparison with the unprocessed clay. In addition, SEM images showed a uniform distribution of the metal oxide nanoparticles on the surface of clay layers accompanied by impregnation of interlayer galleries. Meanwhile, ICP and EDX elemental analyses from pristine clay and produced sample revealed the presence of Ce and Zr elements in the prepared composite. The results clearly confirm the successful encapsulation of CeO2 and ZrO2 nanoparticles into pillared clay galleries. |
