Inorganic nickel-based nanocomposites

Nanocomposites have become hot issues in the field of nanomaterials due to their unique physical and chemical properties. As an important transitional metal nanomaterial, nickel material has been widely used in magnetics, electrochemistry, catalytic chemistry and other fields. The composites of nickel and other metals or oxides with improved inherent properties would show novel properties by the synergy of composition and nanostructure. Therefore, it is of scientific significance to study the nickel-based nanocomposites. Because of the differences of the combining positions and methods for different components in various nanostructures, the progress of nickel-based nanocomposites is reviewed according to three main structures, which are core-shell structure, supported structure, and multisegment nanowires. Based on the introduction to the various synthetic methods and structures, we summarize the advantages and disadvantages of these methods and composite structures, as well as probable applications. It will be helpful for preparing other similar nanocomposites.
