Abstract

In this work, the ZnO spherical nanoparticles with a diameter in the range of 10-30nm have been prepared via mechanochemical oxidation of metallic Zn powders treated in a vibratory ball mill in the presence of air and liquid nitrogen. The as-prepared nanocrystals were characterized by XRD, HR-TEM, FTIR, XPS, and UV-vis spectroscopy. The results show that metallic zinc powder is completely converted to nanocrystalline ZnO within 48h of cryomilling. The XPS analysis confirms the presence of incorporated nitrogen as well as Zn(OH)₂ and carbonate species formed on the reactive structurally-disordered surface shell of the as-prepared nanoparticles. Compared with the pure ZnO, the light absorption by the as-prepared ZnO nanocrystals was shifted to longer wavelengths.
