“…The synthesized nanoparticles were applied for dyesensitized solar cells application. The shifting of absorption edge to lower wavelength and increasing of the band gap is due to the quantum size confinement [58]. Alla et al [59] studied the improvement in electric properties of zirconium substituted Co 3 O 4 nanoparticles produced by the single-step microwave refluxing method.…”

The newest achievement in the synthesis of cobalt oxide nanoparticles are considered. Cobalt oxide nanoparticles have attracted a great attention due to their uncommon properties and application in a supercapacitor, optoelectronic device, Li-ion battery gas sensor and electrochromic devices. Recently, nanostructured transition metal oxides with valuable properties have become a new class of materials for many technological fields. Cobalt oxide nanoparticles obtained from various precursors show different size distribution as well as different optical, electrical, magnetic, and electrochemical properties. A reduction in particle size to nanometer-scale leads to changes in properties compared to bulk ones due to quantum size effects. Depending on the application area, the choice of an appropriate synthesis method for nanoparticles with desirable properties is a crucial factor. This work aims to provide additional information on the synthesis methods and properties of cobalt oxide nanoparticles

“…In particular, significant works have already been made in recent years to improve the synthesis methods for the preparation of CuCr 2 O 4, and La doped CuCr 2 O 4 semiconductor nanostructures. Nonetheless, even now there is a shortage of study on optical characteristics, which have a significant impact on its contributions in microelectronic areas, as stated in the research article [ 10 , 11 , 12 , 13 ]. According to that, we have synthesized pristine CuCr 2 O 4, and different concentrations of La doped CuCr 2 O 4 nanostructures.…”

“…The attractive properties of graphene such as high surface area, two-dimensional sp 2 carbon atoms, low density, and exceptional electrical conductivity have received enormous attention in diverse applications primarily when decorated with nanoparticles. Specifically, the high charge carriage mobility and specific surface area of graphene offer broad range of applications such as in catalysis, sensors, drug delivery, solar panels, DNA sequencing, electronics, and energy storage [30,31]. It has been reported that the enhanced electrochemical activity of the graphene-based electrode is due to the presence of several functional groups at the edge planes in the graphene sheet [32].…”

Transition metal oxide-based magnetic nanocomposites attract great attention due to their unique properties and applications in the field of energy storage. Herein, we present a facile microwave procedure for the synthesis of CuFe2O4 (CF) and CuFe2O4 incorporated with reduced graphene oxide CuFe2O4/rGO (CG) as potential electrode materials for hybrid supercapacitor. The structure and morphology of CF and CG nanoparticles are examined. The electrochemical performance is studied in 6 M aqueous KOH electrolyte using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) techniques. The attractive CG nanocomposite exhibits high specific capacity of 800 C/g at a current density of 2 A/g and better cycling stability when compared to pure CF, due to the formation of nanostructure composed of ferrite nanoparticles homogeneously incorporated onto rGO sheets. Furthermore, the practicability of CG electrode is investigated by the fabrication of CG and activated carbon. The hybrid supercapacitor device shows excellent electrochemical performance with specific energy of 18.3 Wh/kg and a specific power of 455 W/kg. It is noteworthy that the cyclic stability is excellent with a capacity retention of ~98% after 3000 cycles manifesting the superiority of CG electrode. The proposed device demonstrates the potential to fabricate other metal oxides with activated carbon via a facile synthesis method for promoting application in energy storage materials and promoting new opportunities of binary nanocomposite.
