Synthesis of nickel nanothorn particles by the hydrothermal method

Abstract

In this study, an investigation was performed of the preparation of nickel nanothorn particles by the hydrothermal synthesis method. The effects of parameters were investigated on the particle shape and size, which were determined by scanning electron microscope (SEM) analysis. The synthesis parameters were hydrazine concentration, heating temperature in autoclave, heating time in autoclave, nickel sulfate concentration, pH, NaCl concentration. The phases contained in the synthesized samples were analyzed by X-ray powder diffraction (XRD) analysis, nickel purity of samples were analyzed by X-ray fluorescence (XRF), and the magnetic properties of the nickel particles were measured by a magnetic hysteresis test. The results showed that nickel nanothorn particles were successfully produced without any surfactant by simple hydrothermal synthesis. As the hydrazine concentration was increased, the thorn length of the nickel particles also increased.
