Abstract

Novel composites of ZnO-nanoparticles and magadiite were successfully prepared by a simple ion-exchange technique in an aqueous suspension of magadiite (Na₂Si₁₄O₂₉·nH₂O) and Zn(NO₃)₂. The TEM and STEM measurements showed that the composites have a structure in which ZnO-nanoparticles with relatively uniform particle sizes are well dispersed within the interlaminar spaces of the magadiite matrix. The particle sizes of the ZnO-nanoparticles were found to depend on the heat-treatment temperature; the average particle sizes are ~ 2.6, ~ 2.8, ~ 4.4 and ~ 4.6 nm, respectively, for the temperatures of 40, 180, 300 and 600 °C. It was also found that the ZnO nanoparticles crystallize and form a single-crystalline particle when the temperature exceeds ~ 300 °C.
