2013年12月1日 · Nickel oxide (NiO) nanoparticles were successfully synthesized by the reaction of nickel chloride with hydrazine at room temperature and thermal decomposition of the precursor nickel hydroxide (Ni(OH) 2) nanoparticles. The products were characterized by X-ray diffraction, Transmission electron microscopy, Fourier transform infrared spectroscopy ...

2009年5月12日 · We synthesized Ni nanoparticles from the thermal decomposition of new precursor nickel 2-hydroxyacetophenato in oleylamine (Scheme 1). In this process, oleylamine was used as both the medium and the stabilizing reagent.

In this study, ultrafine nickel oxide nanoparticles (NiO NPs) were well synthesized using a simple wet chemical method under low temperature, 300 °C. An Ni (OH) 2 precursor was well precipitated by dropping NH 4 OH into an Ni (Ac) 2 solution.

2020年3月1日 · The structural analysis is confirmed by XRD analysis and the optical absorption study was done by UV–vis analysis. The FTIR confirms the presence of varies functional group in the compound. SEM with EDAX gives the morphological and …

2024年12月9日 · The present work aims at an environmentally benign, economically viable, and novel approach for the synthesis of nickel oxide (NiO) nanoparticles (NPs), reduced graphene oxide (rGO), and rGO/NiO nanocomposite (NC) using Averrhoa Bilimbi (A. Bilimbi) fruit extract as a reducing agent.

The NiO nanoparticles with the size of 9-30 nm were prepared by solid state method using nickel acetate and sodium hydroxide as the raw materials, and Tween 80 as the dispersant. The structure, morphology, size, and infrared and UV-Vis spectra were characterized by XRD, TEM, FTIR and UV-Vis, respect …

2022年4月25日 · Here, an amorphous and dopant-free inorganic material, Ni 3+ -rich NiO x, is reported to be fabricated by a novel UV irradiation strategy, which is facile, easily scaled-up, and energy-saving because all the processing temperatures are below 82 ℃. The as-prepared NiO x film shows highly improved conductivity and hole extraction ability.

2024年4月4日 · In the current work, efficient self-powered UV–vis-near-infrared (NIR) broadband NiO/Si heterojunction photodetectors have been fabricated by room-temperature spin-coating synthesis of a wide bandgap NiO nanocrystal thin film on an n-type Si substrate.

2018年8月22日 · Moreover, UV-Vis absorption spectroscopy is one of the most important methods to reveal the energy structures and optical properties of semiconductor nanocrystals. Bulk NiO has a maximum absorption peak centered at about 320–350 nm that accounts for an optical band gap of 3.6–4.0 eV.

2019年8月24日 · This contribution reports on the synthesis and also compares the main physical properties of nickel oxide nanoparticles (NiO NPs) synthesized by a completely green process using Gymnema sylvestere plant extract and sodium hydroxide as an effective reducing agent for co-precipitation method.
