Preparation and Characterization of Prism-Like ZnO with Pore Structure

Abstract

Porous zinc oxide microprisms constructed by connected nanoparticles have been successfully prepared by thermal decomposition of the Zn-N₂H₄ complexes precursor at 600 ºC for 1 h in air, which was synthesized in advance using Zn(CH₃COO)₂·2H₂O as zinc source and hydrazine hydrate as complexing agent through a room-temperature coordination-precipitation technique. The morphology of ZnO inherit that of the precursor. The products were characterized by X-ray diffraction, energy dispersive X-ray spectrometry, field-emission scanning electron microscopy, UV-visible absorption spectrum and photoluminescence spectrum.
