Abstract

The invention discloses a preparation method and application of manganese doped magnetic nickel oxide, and relates to the technical field of preparation and application of composite magnetic oxide. The preparation method is characterized by growing flaky manganese doped magnetic nickel oxide on a foamed nickel base through a hydrothermal method, wherein manganese enters the crystal lattice of the nickel oxide to substitute nickel. The preparation method disclosed by the invention achieves a favorable manganese doping effect; the manganese doped magnetic nickel oxide disclosed by the invention has the characteristics that the magnetic saturation value is high, and the coercive force value and the value of residual magnetism are not influenced by other components; and the preparation method disclosed by the invention has the advantages of simple equipment process, low cost, high purity, high yield, uniform morphology and small size, and can be widely used in the aspects of acousto-magnetic materials and electromagnetic materials.

Description

technical field [0001] The invention relates to the technical field of preparation and application of composite magnetic oxides, in particular to a preparation method and application of manganese-doped magnetic nickel oxide. Background technique [0002] Magnetic nanoparticles have a wide range of applications, including magnetic fluids, catalysts, biotechnology, biomedicine, nuclear magnetic resonance imaging, data storage, and environmental remediation, and thus have aroused great interest among researchers. In most envisaged applications of magnetic nanoparticles, the performance of the particles is best when the size is smaller than a critical value. Different materials have different particle sizes, but most of them are between 10 and 20nm. [0003] However, in this size range, storage of nanoparticles for too long can lead to inherent instability problems in nanomaterials. Such small particles, due to their large surface area and high volume ratio, tend to reduce thei...
