Synthesis and Thermal treatment of Zn-Cr and Ni-AL Nanoparticles: Structural and Morphological Characterization

Abstract

Layered double hydroxides of Zn-Cr and Ni-AL were synthesized by co-precipitation technique. thermal treatment product(MMO) was made at (600 )°C. In (XRD) results all samples Polycrystalline. The results of (FE-SEM) show that subsequent heat treatments of Zn-Cr LDHs and Ni-AL LDHs at 600 °C lead to an increase of the nanoparticles size to 51.53 nm and 51.17 nm, respectively. AFM images show a good distribution for nanoparticles on the surface and, the particle size increases after heat treatment at 600 °C. low cost as well as simple preparation for prepared Layered double hydroxides offers an ideal way for obtain nanoparticles with small crystallite sizes, the high crystallinity and large surface area.
