“…The synthesis of NiO NPs comprised two stages . The first stage was carried out by slow addition of 17.9 mmol NaHCO 3 (in 10 mL distilled water) to 17.7 mmol NiCl 2 (in 10 mL distilled water) to form Ni(OH) 2 under vigorous stirring.…”

Nanocomposite solid polymer films based on the poly(exo-N-phenyl-7-oxanorbornene-5,6-dicarboximide) (PPhONDI)/ LiClO 4 /NiO system have been designed, and the effect of inorganic NiO nanofiller in different amounts on the film properties has been examined. The exo-PPhONDI/LiClO 4 /NiO polymer system is the first solid nanocomposite polymer electrolyte film example based on a ring-opening metathesis polymerization (ROMP) host polymer. The NiO nanoparticles were prepared by two-step chemical syntheses, and the thermoplastic host polymer, exo-PPhONDI, was synthesized via ROMP. Composite polymer films were prepared by the solution-casting method. The amount of nanoparticles was varied from 1 to 15 wt % of NiO. The conductivity of the nanocomposite solid polymer systems was influenced by the NiO nanofiller concentration. The composite films based on exo-PPhONDI ROMP polymer with the highest conductivity were achieved for the composition with 8 wt % of NiO nanofiller and 10 wt % of LiClO 4 dopant. The prepared films were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy (SEM). The SEM results showed that the filler was well distributed in the polymer matrix.

Highly ordered mesoporous molecular sieves AlMCM‐41 and a new NiO/AlMCM‐41 nanocomposite were synthesized using a sol–gel method. Fourier transform infrared (FT‐IR) spectroscopy, X‐ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX), and N2 adsorption desorption analyses were used to examine the structure, morphology, size and phase composition of the synthesized NiO/AlMCM‐41 nanocomposites. AlMCM‐41 embedded with NiO nanoparticles was subsequently prepared using different nickel loadings in a direct synthetic route. The results show the successful deposition of NiO nanoparticles onto the framework of AlMCM‐41. AlMCM‐41 provides enormous benefits such as environmentally safe, economic viability and porosity when used as support for NiO nanoparticles. The excellent catalytic activities of AlMCM‐41 and NiO/AlMCM‐41 were investigated for the reduction of nitrophenols (4‐NP, 2‐NP) to aminophenols (4‐AP, 2‐AP) in water at ambient temperature. The best observed performance of reduction of NP with 100% conversion into analogous amino derivatives occurred within 6 min with an estimated rate constant of 0.46 min−1. The efficiency of reduction was observed to increase as a function of NiO enrichment. The NiO/AlMCM‐41 nanocomposite could be recycled and reused up to five times without noticeable change in its structure and activity. These properties make NiO/AlMCM‐41 nanocomposite an ideal platform to study various heterogeneous catalytic processes which can have application in purification, catalysis, sensing devices, and green chemistry.
