“…Carbon nanocomposite materials containing metal nanoparticles such as Ni, Co, or Cu or their oxides are appealing for a wide range of applications, including components of scatter radiation absorbent media, heterogeneous catalysts for petrochemical processes, biomedicine, supercapacitor electrode materials and magnetic resonance tomography [107,108]. Metal-carbon nanocomposites with very promising physical, chemical, and mechanical properties are of particular interest to researchers as heterogeneous catalysts for a variety of chemical processes.…”

The rapid economic growth and enormous expansion of the portable electronics market generate a significant need for renewable energy sources, energy storage, and energy conversion technologies. Supercapacitors have emerged as a viable technology for storing renewable energy sources to meet this demand. Recently novel Transition metal oxides/carbon materials (TMC) based electrode materials attracted attention of research community working in supercapacitor field. Redox-active materials, like transition metal oxides, conductive polymers, add pseudo capacitance through quick, reversible redox reactions, and carbon-supported materials Due to their excellent physicochemical stability, large specific surface area, adaptable pore shape, and high electrical conductivity, it has been extensively utilized in supercapacitors (SCs). Of nickel oxide/active carbon composites as electrode materials for supercapacitors are examined in this review article. This review will provide a comprehensive and up-to-date summary of materials composite investigated as prospective electrode in the creation of efficient supercapacitors, along with their respective production processes and electrochemical properties addition, this article will introduce synthesis of supercapacitor electrode composite and fundamental parameters that influence supercapacitor performance.

“…The majority of the authors in this field indicated that these fuels serve as reducing and regulating agents for bio-reduction reactions in the creation of various nanoparticles using the combustion method [1,21]. Contrarily, carbon nanocomposite products containing metal nanoparticles such as copper and cobalt, as well as nickel or its oxides, are an excellent substitute for use in a wide range of applications involving magnetic resonance tomography and biomedicine, electrode materials over super capacitors, heterogeneous catalysts for petrochemical processes, and dispersed radiation-absorbing media [22]. A core/shell structure of Ni-NiO, encapsulated in carbon nanospheres (CNS) and coated with few-and multi-layered graphene (FLG and MLG) was prepared using the chemical vapor deposition (CVD) method [23].…”

An entirely novel and creative technique was employed for producing magnetic Ni–NiO@C nanocomposites, and it was based on the utilization different amounts of finely ground and fully dried olive leaf powders. The resulting nanocomposites were identified and characterized by XRD, FTIR, SEM, EDS, TEM, and Raman techniques. The magnetic and surface characteristics of the composites, as it developed, were further evaluated using the Vibrating-Sample Magnetometer (VSM) and Brunauer–Emmett–Teller (BET) techniques. The results confirmed the success of preparing a Ni–NiO@C nanocomposites, each containing Ni and NiO in crystalline form. Through the morphology of the resulting composites, determined on the basis of an SEM analysis, it became clear to us that the particles were of a semi-spherical shape, with a clear grouping and a definition of their grain boundaries. Comparably, a TEM investigation demonstrated that the composites had a core–shell structure. The surface area of the investigated composites increases as the content of dried olive leaf powders increases due to a significant increase in the total pore volume. These composites illustrated low magnetism (4.874 and 8.648 emu/g) and coercivity (55.203 and 39.639 Oe) for a number of reasons, which will be explained.
