Effect
of the initial solution on the morphology of nickel oxide nanoparticles
obtained by spray pyrolysis
Abstract
NiO powder was synthesized by spray pyrolysis of aerosols of
glycine-nitrate aqueous solution. Influence of initial solution on the
morphology of nanostructured microspherical particles of nickel oxide was
studied. It was shown the way of formation of hollow microspheres with the
diameter from 0.5 to 5 µm, which walls consist of 10-20 nm particles. It was
found that addition of glycine in the initial solution allows to achieve
uniform porous structure of microspheres and significantly increase their
surface area. The X-ray diffraction shows that glycine did not contaminate the
final product.
Key words: spray pyrolysis, microspherical nanoparticle, nanopowders, nickel
oxide, nanoparticles, nanopowder.
