In this study, a nanometer-size material CuFe2O4 was synthesized by a low-temperature hydrothermal reaction of CuCl2·2H2O, FeCl2·4H2O and urea (CH4N2O) with various weight ratio between CuCl2 and FeCl2 namely 1:1, 1:2, 2:1 and 2:3, at 200°C for 6 h. The obtained powder was annealed at 300°C for 1 h. Various characterization methods, namely, Field-Emission Scanning Electron Microscopy (FESEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Vibrating Sample Magnetometer (VSM) analysis were used to investigate the properties of the CuFe2O4 nanomaterials. FESEM images revealed that the hydrothermal synthesis of CuFe2O4 resulted in a nanocubic structure with particle size of 45 nm; meanwhile XRD analysis indicated the crystalline nature of CuFe2O4 without any other impurities. In addition, FTIR and VSM allowed explaining the chemical and magnetic properties of nanocubic CuFe2O4.
