tailieunhanh - Synthesis and characterization of nano-structured perovskite type neodymium orthoferrite NdFeO3

In this investigation, neodymium orthoferrite (NdFeO3) nanoparticles has been synthesized through ultrasonic method in the presence of octanoic acid as surfactant. This method comparing to the other methods is very fast and it does not need high temperatures during the reaction. | Synthesis and characterization of nano-structured perovskite type neodymium orthoferrite NdFeO3 Current Chemistry Letters 6 2017 23 30 Contents lists available at GrowingScience Current Chemistry Letters homepage Synthesis and characterization of nano-structured perovskite type neodymium orthoferrite NdFeO3 Mostafa Yousefia Samaneh Soradi Zeidb and Mozhgan Khorasani-Motlaghc a National Iranian Oil Products Distribution Company NIOPDC Zahedan Region Zahedan Iran b Department of Mathematics Faculty of Mathematics University of Sistan amp Baluchestan Zahedan Iran c Department of Chemistry Faculty of Science University of Sistan amp Baluchestan Zahedan Iran CHRONICLE ABSTRACT Article history In this investigation neodymium orthoferrite NdFeO3 nanoparticles has been synthesized Received August 21 2016 through ultrasonic method in the presence of octanoic acid as surfactant. This method Received in revised form comparing to the other methods is very fast and it does not need high temperatures during the October 24 2016 reaction. The spherical NdFeO3 nanoparticles with an average particles size of about 40 nm Accepted 24 October 2016 can be obtained at a relatively high calcination temperature of 800 C for 4 h. Also product Available online obtained by this method are uniform in both morphology and particles size. The phase 25 October 2016 composition morphology lattice parameters and size of particles in these product are Keywords characterized by Fourier transform infrared FT-IR spectroscopy X-ray diffraction XRD Nanoparticles scanning electron microscopy SEM and energy dispersive X-ray spectrometer EDX . The Ultrasonic irradiation XRD analysis reveals only the pattern corresponding to perovskite type NdFeO3 which Octanoic acid crystallizes in the orthorhombic structure. Energy dispersive X-ray analysis confirms the Perovskite elemental compositions of the synthesized material. NdFeO3 2017 Growing Science Ltd. All rights reserved. 1. .
