Preparation and Characterization of Nanocrystalline NiO in Mixed Solvent

Abstract

Abstract: NiOnanocrystalline materials were prepared by decomposing a deep green non-crystal precursor at 4OO℃.The precursor was obtained in alcohol-water mixed solvent bythe reaction of Ni(NO₃)₂ and NH₄HCO₃. XRD, TG, DTAand TEMwere used to character-ize the nanometer NiOand its precursor.The result show that the NiOfine particles arenon-agglomerated, spherical and well dispersed with the average size of 7 nm.The problemof agglomeration in c0nventional solution method is Overcomed by this convenient method.

Key words: Nanocrystalline, Nickel oxide, Preparation
