Size-Controlled Synthesis of Magnetite Nanoparticles ...

2019-3-15Monodisperse magnetite nanoparticles have been synthesized by high-temperature solution-phase reaction of Feacac3 in phenyl ether with alcohol, oleic acid, and oleylamine. Seed-mediated growth is used to control Fe3O4 nanoparticle size, and variously sized nanoparticles from 3 to 20 nm have been produced. The as-synthesized Fe3O4 nanoparticles have inverse spinel structure, and their ...

Synthesis of CaOH 2 nanoparticles by wet chemical

This Letter reports a process of preparation and characterisation of CaOH2 nanoparticles without using any surfactant. CaOH2 is frequently used as precipitant, catalyst, paint, toxic-waste remediation agent, adsorbent and so on. To prepare stable CaOH2 nanoparticles, a simple hydrolysis method was applied using CaNO324H2O as the precursor, aqueous NaOH as the precipitant and ethane-1 ...

2019-3-12A novel nonaqueous route has been applied for the preparation of nanocrystalline magnetite. In a simple one-pot reaction process, ironIII acetylacetonate was dissolved in benzyl alcohol and treated in an autoclave between 175 and 200 C. This approach leads to monocrystalline magnetite particles with sizes ranging from 12 to 25 nm, as evidenced by X-ray analysis, HRTEM, and Raman and ...

Magnetic properties of hematite Fe2O3

Abstract. Using the sol-gel method we synthesized hematite Fe 2 O 3 nanoparticles in a silica matrix with 60 wt of hematite.X-ray diffraction XRD patterns and Fourier transform infrared FTIR spectra of the sample demonstrate the formation of the Fe 2 O 3 phase and amorphous silica. A transmission electron microscopy TEM measurements show that the sample consists of two ...
