Structural and thermal properties of pure and chromium doped zinc oxide nanoparticles

Highlights Pure ZnO and Cr–ZnO nanoparticles have been synthesized using a facile and cost effective technique. The as prepared samples of pure ZnO and Cr–ZnO nanoparticles show wurtzite structure. Cr doped ZnO nanoparticles showed a higher surface area than that of un-doped ZnO nanoparticles. The synergetic effect of Cr and ZnO nanoparticles attributed to good thermal stability and high surface area.
