Synthesis and characterization of nano‐sized NiO and its surface catalytic effect on poly(vinyl alcohol)

Abstract

Nickel oxide (NiO) nano particle is synthesized by Ultrasound assisted one pot method and thus synthesized nano NiO is mixed with poly(vinyl alcohol) (PVA) to prepare the PVA/NiO nanocomposite. The influence of the composition on the structural modification on the composite is evaluated. The particle size and morphology of NiO nano material is confirmed by HRTEM. The structure and properties of the PVA/NiO nanocomposite material are characterized by FTIR, XRD, UV-Visible spectroscopy, DSC, TGA, and HRTEM. The synthesized PVA nanocomposite underwent hydrolytic oxidation reaction assisted by the effect of nano-sized NiO.

Unusual magnetic properties of NiO nanoparticles embedded in a silica matrix

“…The nickel oxide (NiO) has attracted much attention and it has been used in magnetic devices, antibacterial applications, catalysis, electrode materials, sensors and electrical devices [9][10][11][12][13][14][15][16][17].…”

Development of nano NiO incorporated nickel–phosphorus coatings for electrocatalytic applications

“…The occurrence of the absorption maxima in the frequency region lying between ω T and ω L (560 cm -1 for NiO) together with the absence of any well defined absorption maxima corresponding to ω T clearly indicates the dominance of surface modes in far IR spectra. The metal-oxygen (M-O) bond was observed at 650 cm -1 [30]. The broad band in the range of 3600-3100 cm -1 is due to the OH stretching of water molecules associated with NiO.…”

“…[16] Various solid acid catalysts with variety of acid sites were considered in many different processes. [20][21][22] We explored the possibility to prepare new spiro compounds with condensation reaction at vigorous stirring of equimolar quantities of ninhydrin and о-phenylenediamine derivatives, then amines and isatoic anhydride were added in presence of (3-oxo- [1,2,4] triazolidin-1-yl)bis (butane-1-sulfonic acid) supported on γ-Fe 2 O 3 (γ-Fe 2 O 3 @Oxo-triazolidin-sultone) in ethanol at 70°C temperature (Scheme 1). Its oxime is a noncytotoxic inhibitor of inflammatory cytokine and of production of nitrogen monoxide.…”
