Anwendungen & Verwendung
Beschreibung
Nickel (II) nitrate hexahydrate appears as green crystals and substantially soluble in water. It is stable, a strong oxidiser, and incompatible with reducing agents. It has wide industrial applications in nickel plating as catalysts and is indirectly associated with other industries of nickel alloy manufacturers, nickel miners, smelters and refiners, nickel platers, and exposure to alloys, for example, in coinage.
Verwenden
Nickel plating, manufacturing of ceramic colorsNickel(II) nitrate hexahydrate is used as a precursor in the manufacturing of other nickel salts and supported nickel catalysts. It finds use as a catalyst in organic synthesis. Further it is used in electroplating and as a mordent in textile dyeing. It is a precursor for preparing nickel sulfide-reduced graphene oxide (RGO) composite powders with high initial capacities and good cycling performance. It can be employed in the preparation of nickel and nickel oxide nanocrystals impregnated O-MWCNTs (oxygen-functionalized multi-walled carbon nanotubes) with potential applications in semiconductor industries. It finds use in improving cycling stability ad rate capability of Li2MnO3.
Herstellung & Synthese
synthetische
Emerald green crystals of the hexahydrate Ni(N03)26H20 crystallize from aqueous solutions at room temperature. These are isomorphous with the corresponding cobalt(II) salt containing the regular octahedral [Ni(H20)6]2+ ions with Ni-O distances = 2.03 A. The tetrahydrate crystallize above 54° and the dihydrate above 85.4°. The pale green anhydrous nitrate can be obtained by dehydration of the hydrate with dinitrogen pentoxide in fuming nitric acid or by the liquid phase reaction of dinitrogen tetroxide with nickel carbonyl [the gas phase reaction gives the nitrite Ni(N02)2] Ni(CO)4+2N2O4 -* Ni(N03)2+2NO+4CO The first product of this latter rather violent reaction is the adduct Ni(NO3)2N2O4 from which the nitrogen tetroxide is removed by heating in vacuo. It can also be prepared by the reaction of dinitrogen tetroxide-ethyl acetate mixtures with nickel(II) chloride. The infrared spectrum shows it to be a typical covalent nitrate. It is involatile and decomposes upon heating in nitrogen to give the nitrite Ni(NO2)2 above 260°.
