MgO thin films have been prepared on substrates by a novel and simple sol-gel method using magnesium nitrate and collusion as starting material. The MgO nano catalyst with good sensor crystallization were obtained after annealing at 100°C Magnesium oxide was prepared by sol-gel method. The method involves the hydrolysis of magnesium alkoxide in the presence of acid or basic catalysts followed by a polyethylene glycol condensation reaction. The synthesized solids were characterized by IR spectroscopy X-ray diffraction electron microscopy, Ultraviolet visible absorbance measurement photoluminescence and Raman scattering spectra. sol gel irradiation the structure and morphology of the MgO particles were analyzed by XRD,These articles were used for FTIR spectroscopic measurement and spectra were collected, In EDS we calculated the peak intensity the SEM the images of metal oxide.
Metals are able to form a large number of oxides. These metal oxides play an important role in many areas of chemistry, physics and material science. An important metal oxide known as magnesium oxide (MgO) having good reactivity is widely used in producing electronics, catalyst, ceramics, oil, paint etc. Magnesium oxide Nano-particle is non-toxic and need a small amount, so it is suitable for the development of flame-retardant fiber additives. In addition, nano magnesium oxide added in fuel can inhibit corrosion. In this communication Magnesium oxide nanoparticles were successfully synthesized by coprecipitation technique at room temperature using magnesium nitrate and sodium hydroxide as a precursor. The morphological investigation of MgO nanoparticles was done by various analytical techniques Scanning Electron Microscope (SEM-EDX) for morphological studies. X-ray Diffraction (XRD) indicates the crystallinity and crystal size of MgO nanoparticle. Fourier Transform Infrared (FTIR) spectroscopy is used for analysing the functional groups of the sample.

During the last decade, it has realized that when materials are synthesized to nanoscale dimensions, they will show new and remarkably improved physical and chemical properties. Due to its wide and major applications, in-depth investigations have been carried out on metal oxide nanomaterials. A significant amount of research is going on in synthesis and characterization of MgO/PVA nanocomposites. Some of the literature has been reviewed to get the idea about the synthesis and characterization of MgO/PVA nanocomposites using sol-gel technique.

Magnesium oxide nanoparticles (MgONPs) have been synthesised by mixing aqueous solutions of magnesium sulphate and sodium hydroxide. The resulting precipitate of magnesium hydroxide was heated strongly to get dry precipitate. Then it was heated strongly at 300 C for hours. The resulted magnesium oxide nanoparticles were characterized by SEM and EDAX. The MgONPs appeared in the form of plates and clusters. The size was in the range of 128 to 187 nm.

Nanosized MgO is a functional material showing a great promise as destructive adsorbent for toxic chemical agents, unique optical electronic, magnetic, thermal, and mechanical properties, as well as in good bactericidal performance in aqueous environments and in the cancer therapy. In this study, MgO nanoparticles are obtained by thermal decomposition of nanosized Mg(OH) 2 , which are synthesized by means of an innovative, time and cost-effective, scalable, and patented method. The nanoparticles are characterized by means of several techniques such as thermal analyses, X-ray diffraction analysis, infrared spectroscopy, transmission electron microscopy, atomic force microscopy, and surface area measurements (BET). After a pseudomorphic decomposition of the hydroxide precursor, pure and crystalline MgO nanoparticles are obtained. These nanoparticles are roughly spherical, monodispersed, and monocrystalline, having size ≤10 nm. Moreover, they exhibited a surface area up to 178 m 2 /g, revealing a bimodal mesoporous distribution with the important part of the pores with dimensions peaked at 4.87 nm.

The present work is focused on the synthesize of MgO nanoparticles using combustion method. The magnesium nitrate is used as a precursor with urea as a fuel. The precursor material is dissolved in 50 ml DI water along with the fuel and the solution is heated at 80°C for 2 h. Then, the solution is transferred to crucible and kept it in the temperature of 500°C. The as-synthesized MgO nanopowders are analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), photo-luminescence (PL) and photocatalytic studies. The XRD results of MgO nanoparticles indicated the cubic structure with the crystallite size of 27 nm. The FESEM studies indicated the formation of MgO crystallites in spherical shape. In addition, MgO nanoparticles are porous and agglomerated. PL spectrum of MgO materials exhibit emission peaks, which indicates the occurrence of band to band transition with the bandgap of 2.9 eV. The photocatalytic degradation of methylene blue dye is evaluated using the as-prepared MgO nanoparticles under UV light. The photocatalytic studies indicate the 75% degradation efficiency of the catalyst after 120 min irradiation. Hence, the MgO Nanoparticles (NPs) can be used for the treatment of effluents from the dye industries .
