Size Controlled Hydrothermal Synthesis and Characterization of Nickel Metavanadate (NiVO3) Nanoparticles

Abstract

In the age of nanotechnology with different enhanced properties, all devices, processes and materials are reduced to smaller and smaller sizes. The controlled morphology of metal oxide nanomaterial is of great importance in electrochemical generation and storage devices. In this paper, we reported the novel synthesis of nickel-based metal oxides from a simple hydrothermal process with numerous shapes. Nanoparticles (NPs) of nickel metavanadate (NiVO₃) have recently attracted considerable attention due to their peculiar properties, such as size-controlled morphology, greater surface area and surface to volume ratio. The morphology and phase of synthesized NiVO₃ NPs was characterized by X-ray diffraction (XRD) and Scanning electron microscope (SEM) as a result, NPs are crystalline, calculated from XRD. Synthesized NPs have been characterized by spectroscopic methods, i.e. FTIR. The size and stability of the NPs was calculated using the nanoparticle analyzer and the zeta potential. The average size of the NPs obtained was 44 nm and the particle size ranged from 18 nm to 110 nm. NPs' negative Zeta potential was found to be −63.3 mV, which confirms stability and dispersion.  The FTIR range revealed the existence of V-O, V=O, V-Ni, Ni-O and V-O-V stretching types.
