Innovation in design and fabrication of energy storage materials has triggered a swift development in capacitive materials. In this regard, two-dimensional grapheme-based spinal metal oxide nanocomposites exhibit quite substantial capacitive potential. Moreover, heteroatom-incorporated graphene nanocomposites improvise the electronic significance of conducive materials. For purpose, copper chromite nanoparticles embedded on graphene oxide (CuCr₂O₄/GO) were developed via co-precipitation method as an efficient energy storage material. CuCr₂O₄ was prepared by simple sol–gel route, whereas GO was synthesized by modified Hummer’s method. Structural crystallinity was analyzed by X-ray diffraction analysis, structural morphology and elemental weight composition indicated by scanning electron microscopy and energy-dispersive spectroscopy, respectively. Bond formation in CuCr₂O₄/GO composite was reflected by Raman band shifts. The photoluminescence measurements were taken for estimation of bandgap. Charge transfer resistance (R_ct) and electrochemical active surface area were obtained from electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV), respectively. Specific capacitance of the as-synthesized nanocomposites was calculated via CV measurements when peak current was observed varying the scan rate in both acidic and basic media. Maximum capacitance of 370.5 Fg⁻¹ achieved corresponded to 0.1 M H₂SO₄ aqueous electrolyte, which is an indication of capacitive energy storage application of as-synthesized nanocomposite. Therefore, it can be conferred that the as-synthesized CuCr₂O₄/GO material could be an effective capacitive material for energy storage applications.

储能材料设计和制造的创新引发了电容材料的快速发展。在这方面，基于二维石墨烯的脊柱金属氧化物纳米复合材料表现出相当大的电容潜力。此外，掺入杂原子的石墨烯纳米复合材料提高了导电材料的电子意义。为此，通过共沉淀法开发了嵌入在氧化石墨烯（CuCr ₂ O ₄ /GO）上的亚铬酸铜纳米颗粒作为一种高效的储能材料。CuCr ₂ O ₄GO 是通过简单的溶胶-凝胶途径制备的，而 GO 是通过改进的 Hummer 方法合成的。结构结晶度通过 X 射线衍射分析、结构形态和元素重量组成分别通过扫描电子显微镜和能量色散光谱进行分析。CuCr ₂ O ₄ /GO 复合材料中的键形成由拉曼能带位移反映出来。进行光致发光测量以估计带隙。电荷转移电阻 ( R _ct) 和电化学活性表面积分别从电化学阻抗谱 (EIS) 和循环伏安法 (CV) 获得。当在酸性和碱性介质中观察到峰值电流改变扫描速率时，通过 CV 测量计算合成的纳米复合材料的比电容。获得的 370.5 Fg ^{-1 的}最大电容对应于 0.1 MH ₂ SO ₄水性电解质，这表明合成的纳米复合材料的电容储能应用。因此，可以认为合成的CuCr ₂ O ₄ /GO 材料可能是一种有效的储能应用电容材料。
