Non‐Aqueous Sol–Gel Approach towards the Controllable Synthesis of Nickel Nanospheres, Nanowires, and Nanoflowers

Abstract

Nickel nanospheres, nanowires, and nanoflowers are synthesized via a facile non-aqueous sol–gel route involving the reaction of nickel acetylacetonate with benzyl alcohol at 200 °C in the presence of varying magnetic fields, as illustrated in the figure. Benzyl alcohol acts as both the solvent and reductant in this system. The nanostructures show substantial enhancement in coercivity as compared to bulk nickel.
