Abstract

It is imperative that composite systems with high performance, low-cost, enhanced simplicity, and scalability be developed in order to convert and store energy. This, however, has been a challenging endeavor throughout the years. In this study, we present a cost-effective, efficient, scale-up-friendly, and environmentally friendly method of producing in situ sandwich layers of ZnO-CuO composite between NiCo₂O₄ nanostructures and nickel foam using lemon peel extract (LPE) during hydrothermal processes. NiCo₂O₄/ZnO-CuO/nickel foam was analyzed using powder X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS). According to XRD and HRTEM studies of NiCo₂O₄/ZnO-CuO/nickel foam, NiCo₂O₄, ZnO, and CuO exhibit cubic, hexagonal, and monoclinic phases, respectively. With NiCo₂O₄/ZnO-CuO/nickel foam as the active anode electrode, an asymmetric supercapacitor has been developed in an alkaline solution of 3 M KOH. At a low current density of 2 Ag⁻¹, the asymmetric supercapacitor exhibited a high specific capacitance of 3614.8 F g⁻¹, a power density of 1549.2 W kg⁻¹, and an energy density of 75.3 Wh kg⁻¹. Upon repeatable 40,000 galvanic charge–discharge cycles, the asymmetric device demonstrated a high specific capacitance retention percentage of approximately 100 to 95 and a columbic efficiency of 98%. Moreover, NiCo₂O₄/ZnO-CuO/nickel foam composite had a low overpotential of 210 mV at 40 mA cm⁻² and a Tafel slope of 70 mV dec⁻¹ for OER in 1 M KOH. During continuous OER measurements over a period of 40 h, NiCo₂O₄/ZnO-CuO/nickel foam composites demonstrated high durability and stability. NiCo₂O₄/ZnO-CuO/nickel foam exhibits good electrochemical performance as a result of its synergetic effects, its high conductivity, its abundant exposed catalytic sites, its oxygen vacancies, and its high durability.

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
