Inorganic Materials Aims and scope

Abstract

Pure hexagonal phase of ZnO nanoparticles have been successfully synthesized via microwave assisted decomposition of zinc acetate precursor in a green solvent, the ionic liquid, 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide in a very short time scale. The ZnO nanoparticles were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and selected area electron diffraction.

The effects of irradiation time and use of the surfactant, cetyltrimethylammonium bromide on the size and morphology of ZnO nanoparticles were examined. Based on the experimental observations, a possible growth mechanism was put forward to explain the formation of ZnO nanoparticles.
