NANOSTRUCTURAL OXIDES AND HYDROXIDES AND METHODS OF THEIR SYNTHESIS

摘要

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention relates to synthesis of nanostructural materials by chemical way. Method involves reagent solution spraying in precede solution up to formation of precipitate of nanostructural oxide or hydroxide. Then precipitate is subjected for thermal treatment and the following treatment by ultrasonic oscillation or treatment by ultrasonic oscillation and the following thermal treatment. This method gives nanostructural alloyed or nonalloyed nickel hydroxide, manganese dioxide and zirconium oxide stabilized with yttrium. Unusual morphological superstructures including clearly distinguished cylinders or nanorods and also novel structures for nickel hydroxide and manganese dioxide can be obtained that comprise assembly of nanostructural fibers, assembly of nanostructural fibers and agglomerates of nanostructural particles and assembly of nanostructural fibers and nanostructural particles. These novel structures exhibit high rates or percolation and high density of active centers that makes their especially suitable for production of catalysts. EFFECT: improved method of synthesis, valuable properties. 66 cl, 40 dwg
