Abstract

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 NiCo 2 O 4 nanostructures and nickel foam using lemon peel extract (LPE) during hydrothermal processes. NiCo 2 O 4 /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…
