Analytica Chimica Acta. The effect of MWCNTs addition on the electrochemical performance. The Journal of Physical Chemistry B36of nanocomposite has been probed thoroughly in a normal three electrode configuration using 2 M KOH electrolyte at.

Conclusion The paper thoroughly discussed the synthesis of NiFe2O4 nanoparticles by the employment of co-precipitation method. That the nanoparticles agglomerated to form spherical-shaped particles was also confirmed and made clear by the SEM analysis. The average particle size of NiFe2O4 nanoparticles was found to be 28 nm. The impact of the frequency and the temperature on the dielectric loss and the dielectric constant for NiFe2O4 nanoparticles was studied. From the dielectric studies it became evident that the frequency negatively impacted as both the dielectric constant and the dielectric loss decreased with increase in the frequency.

A study of the magnetic properties was also carried out using VSM measurements.

In the presence of surfactants, the crystallinity of NiFe2O4 nanoparticles decreased in comparison with surfactant- free prepared samples. All of the nickel ferrite nanoparticles were superparamagnetic at room temperature. Because of these properties, the spinel ferrites have many technical applications, such as in photoelectric devices [ 3 ] catalysis [ 4 ], sensors [ 5 ], nano devices [ 6 ], microwave devices [ 7 , 8 ] and magnetic pigments [ 9 ].

Remarkable electrical and magnetic properties of ferrites depend upon the nature of the ions, their charges and their distribution among tetrahedral A and octahedral B sites [ 10 ]. Nickel ferrite is one of the versatile and technologically important soft ferrite materials because of its typical ferromagnetic properties, low conductivity and thus lower eddy current losses, high electrochemical stability, catalytic behavior, abundance in nature, etc[ 8 ].

This ferrite is an inverse spinel in which eight units of NiFe2O4 go into a unit cell of the spinel structure. Half of the ferric ions preferentially fill the tetrahedral sites A-sites and the others occupy the octahedral sites B-sites [ 11 ]. The synthesis of spinel ferrite nanoparticles has been intensively studied in the recent years and the principal role of the preparation conditions on the morphological and structural features of the ferrites is discussed [ 13 - 16 ].

Large-scale applications of ferrites with small particles and tailoring of specific properties have prompted the development of widely used chemical methods, including hydrothermal [ 10 ], sonochemical reactions [ 17 ], sol-gel methods[ 18 ], microwave plasma [ 19 ], co-precipitation [ 20 ], microemulsion methods [ 21 ], citrate precursor techniques [ 22 ] and mechanical alloying [ 23 ] for the fabrication of stoichiometric and chemically pure spinel ferrite nanoparticles.

The hydrothermal route is one of the most commonly used techniques owing to its economics and high degree of compositional control. In addition, the hydrothermal synthesis does not require extremely high-processing temperature or sophisticated processing. In this work, nano crystalline nickel ferrite, NiFe2O4, was successfully prepared via reaction between metal chlorides in ethylacetate solution with and without surfactant assisted processes.
