This work depicts the synthesis of well-defined nanosheets of cuprous delafossite (CuCrO2) nanoparticles (NPs) on Ni foam by a low temperature hydrothermal method and its possible application as an electroactive material for the fabrication of supercapacitors. Our synthetic strategy describes a simple and facile method to obtain CuCrO2 delafossite material with zero dimensionality. Herein, X-rays diffraction, UV-Vis absorption, FTIR and Raman spectroscopic analysis are used to study the crystal nature, structure, composition and quality of CuCrO2 delafossite NPs. X-rays photoelectron spectroscopy (XPS) investigates the chemical composition and oxidation state of elements present in the synthesized CuCrO2 delafossite NPs. As an electrode material for electrochemical supercapacitor application, it is expected that the synthesized CuCrO2 delafossite NPs will show unique features such as large interior spaces, high specific surface area and low density, which might help to improve the electrochemical property by enhancing the surface and/or interface reaction. |
