EVOLUTION OF NANOSHEET STRUCTURES OF PSEUDOBOEHMITE IN THE OXIDATION OF WATER AL AND AL/ALN NANOPARTICLES
In the present paper we present the results of a study of the evolution of nano-sheet structures of nanoparticles in the oxidation of water Al and Al / AlN. The oxidation of nanoparticles is characterized by changes in pH 4 stages of the reaction medium. Morphology of intermediate oxidation products extracted at each stage was study with transmission electron microscop. It was shown that due to oxidation at the oxide film Al nanoparticles formed hollow spheres coated mesoporous sheath of nanosheets pseudoboehmite. As the result of oxidation of Al/AlN nanoparticles, was formed agglomerate of pseudoboehmite nanosheets without hollow. The composition and texture of the product water oxidation Al and Al / AlN identical.
