“…Actually, the diverse available methods to prepare CuO-CuFe 2 O 4 nanocomposites have been previously published such as co-precipitation, solid state method, oxalate precursor and radio-frequency (RF) sputtered methods [7,8,15,16]. From the best of our knowledge; this the first report on synthesis of CuO/CuFe 2 O 4 nanocomposite via a simple microemulsion.…”

“…These doped nanomaterials have been demonstrated to show co-existence of different physical properties like semiconductor and ferromagnetic materials [6][7]. For instance, it is reported that the addition of Fe 3+ ion in copper oxide leads to form CuO/CuFe 2 O 4 nanocomposites [8]. Integrating CuO with CuFe 2 O 4 with n-type semiconducting property has been proved to enrich and the optical, magnetic, electrochemical and electrical properties.…”

“…Integrating CuO with CuFe 2 O 4 with n-type semiconducting property has been proved to enrich and the optical, magnetic, electrochemical and electrical properties. Actually, it is necessary to enhance the magnetic properties of CuO for magnetic storage media and magneto-electronic devices [8][9][10]. Furthermore, the presence of CuFe 2 O 4 magnetic material during CuO as application photocatalyst helps in the regeneration of the catalyst after the processing which can be easily removed from the solutions [9,11,12].…”

“…Previously, different researchers have worked to improve the photodegradation activity of CuO by doping it with different elements. For example, Shaban et al investigated the influence of Fe doping on CuO and found higher activity due to Fe doping [19]. Nuengruethai et al prepared Ce-doped CuO nanostructures and evaluated their photocatalytic activity against methylene blue (MB) [20].…”

Recently, metal oxide-based nano-photocatalysts have gained a great deal of attention in waste water remediation due to their outstanding properties. In this report, a novel Mo-doped CuO nanomaterial was successfully prepared and utilized for the degradation of methylene blue water pollutant. The molybdenum content was varied from 1–5 wt.% to obtain the desired modified CuO based nanomaterials. The crystalline structures of as prepared materials were investigated using the XRD technique, which explored the successful fabrication of monoclinic-structure-based CuO nanomaterials. For morphological studies, SEM and HRTEM were used, which proved the successful preparation of nanoparticles-based material. SAED was used to check the crystallinity of the sample. EDX and XPS analyses were performed to evaluate the elemental composition of Mo-doped CuO nanomaterials. The optical characteristics were explored via UV-vis and PL techniques. These studies showed that the energy bandgap of CuO decreased from 1.55 eV to 1.25 eV due to Mo doping. The photocatalytic efficiency of Mo-doped CuO nanomaterials was evaluated by degrading methylene blue (MB) under visible light-irradiation. Among different Mo-doped CuO based nanomaterials, the 4 wt.% Mo-doped CuO sample showed the highest degradation activity against MB dye. These results verified that the optimized material can be used for photocatalytic applications, especially for the purification of waste water.

In the last decade the metal oxide NPs are the promising applications in the research field. The lot of methods to available in the synthesis of NPs, but co-precipitation method is very simple, low cost and environmental friendly. The different percentage (Fe 2+ ) doped copper oxide (CuO) NPs prepared by co-precipitation method. XRD pattern confirms the samples are crystalline in monoclinic structure identified by the JCPDS Card. No (80-0076). The doping concentration increases the crystalline size also decreases. CuO NPs based functional groups are identified from FTIR spectra. UV-Vis Spectroscopy the Fe doped CuO has a band gap is determined in the range of 3.57 to 3.62 eV. The Pl emission spectra revealed a blue shift after introducing Fe into CuO structure, from these studies is better for the preparation of CuO nanoparticles. SEMthe surface morphology of the as prepared CuO nanoparticles has identified by SEM studies the indefinite and closely packed grain is observed. The EDAX spectra showed presence copper, Fe and oxygen atoms.
