Abstract In this work at the rst step, ZnFe2O4
nanoparticles were synthesized via hydrothermal method. It was investigated that the size and morphology of ZnFe2O4
was affected by the ligand and reductant agent. 2-hydroxyacetophenone was used as a good capping agent to produce uniform rice-like nanostructure. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, Fourier transform infrared spectroscopy. Alternating gradient force magnetometer was demonstrated ferromagnetic behavior of ZnFe2O4 nanoparticles. The photocatalytic behavior of ZnFe2O4 nanoparticle (band gap 2 eV) was evaluated using the degradation of Rhodamine B under visible light irradiation (81 %). A composite was obtained while the ZnFe2O4 nanoparticles were added to polystyrene. The inuence of ZnFe2O4 on the thermal properties of polymer matrix was studied using thermogravimetry analysis. Thermal decomposition of the polystyrene was shifted towards higher temperature (60 C) in the presence of the ZnFe2O4 nanoparticles.
1 Introduction
Spinel ferrites have received further interest in technologically anchored modern society owing to their promising application in microwave adsorption [1], electrode materials [2], environmental remediation [3, 4] and drug-loading
materials [5]. In the last few decades, the transition metal oxide based nanoferrites with a molecular formula MFe2O4
(M = Zn, Ni, Co, Mg, Mn, Cu, etc.) have become technologically and scientically important owing to their size-dependent physical and chemical properties [6]. The methods of synthesizing ferrite with different morphologies have been widely studied [7] including prepared nanoparticles NiFe2O4 and nanorod BaFe12O19 by solgel method [810], synthesized Ni0.5Zn0.5Fe2O4 and CoFe2O4 nanowire/tube by
the solgel template method [11], fabricated nanobre CuFe2O4 by electrospinning method [12] and prepared
NiFe2O4 nanorods via a PEG-assisted hydrothermal route [13]. Among these methods, hydrothermal route has been known as one of the most promising synthetic strategies for synthesis of various nanoparticles, as well as economical and convenient way to control the compositional, morphology and crystals [1416].
