“…Nanoscale MgO possesses unique optical, electronic, magnetic, thermal, mechanical and chemical properties due to its characteristic structures (Ramanujam and Sundrarajan 2014). Magnesium oxide is an important functional metal oxide that has been widely used in various fields, such as catalysis, refractory materials, paints, and superconductors (Salem et al 2015). In the literature, there are several methods for the synthesis of nano-sized MgO particles, including the sol-gel method, chemical gas phase deposition, laser vaporization, hydrothermal synthesis, and combustion aerosol synthesis (Mirzaei and Davoodnia 2012).…”

The synthesis of metal oxide nanoparticles with the use of plant extract is a promising alternative to traditional chemical methods. The aim of this work was to fabricate MgO nanoparticles using the Artemisia abrotanum herb water extract. The biologically synthesized MgO nanoparticles were characterized by UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) with EDS profile and transmission electron microscopy (TEM). XRD studies confirmed that pure monoclinic crystallite structures of MgO nanoparticles were formed. The average size of MgO nanoparticles was found to be 10 nm. EDS profile confirmed the signal characteristic of magnesium and oxygen. FTIR analysis confirmed the presence of active compounds responsible for the stabilization of MgO nanoparticles. The synthesized nanoparticles showed good catalytic activity in the reduction of methyl orange (MO). MgO nanoparticles also exhibit very good antioxidant properties.

“…In our present research, we had adopted the second strategy, where CuO nanoparticles were firstly prepared by the co-precipitation method [27] followed by sol-gel coating process. The mesoporous layer can be deposited either directly onto the copper oxide cores or the copper oxide crystals can be precoated with a dense silica layer via a modified Stöber method [18] followed by coating with mesoporous layer.…”

Silica-or meso-silica-or silica-meso-silicacoated copper oxide microspheres were prepared based on base hydrolysis of tetraethyl orthosilicate in the presence of CuO and CTAB. Functionalization with amine or thiol organofunctional groups was conducted onto the surface of silica-meso-silica-coated copper oxide microspheres (Scheme 1). The silica-coated CuO composites and their amine-or thiol-functionalized materials have been characterized by TEM, XRD, TGA, FTIR and UV/Vis. TEM analysis showed that the CuO nanoparticles were encapsulated and dispersed into the silica or meso-silica microspheres. XRD analysis indicated that the size of CuO nanoparticles has decreased after coating with silica precursors. TGA and FTIR results indicated that the mesosilica-coated copper oxide materials have been successfully grafted by amine and thiol organofunctional groups. Graphical Abstract

Dolomite is one of the most important resources for producing periclase (MgO) nanoparticles, which are of highly demanded in many industrial applications. For that reason, this study investigated to prepare MgO nanoparticles from dolomite through pyrohydrolysis–calcination processes. Each obtained product was characterized using X‐ray fluorescence, scanning electron microscope, X‐ray diffraction, and wet chemical and image processing analyses. Synthetic aragonite (CaCO3) crystals and CO2 gas were obtained as by‐products. The experimental results indicate that each obtained product was identified as a periclase mineral, and the production temperature played a curial role for producing pure MgO nanoparticles. However, the reactivity and particle size distribution of each product were strongly influenced by the production temperature. The particle size of the product obtained at various temperatures ranged from 180.05 nm to 6 μm depending on the production condition. We determined that the calcination process should be conducted to produce MgO nanoparticles. The proposed method brings a new perspective to researchers for the production of MgO nanoparticles from dolomite. © 2017 Curtin University and John Wiley & Sons, Ltd.
