Engineered Cu0.5Ni0.5Al2O4/GCN Spinel Nanostructures for Dual-Functional Energy Storage and Electrocatalytic Water Splitting
The rapid growth in population and industrialization have significantly increased global energy demand, placing immense pressure on finite and environmentally harmful conventional fossil fuel-based energy sources. In this context, the development of hybrid electrocatalysts presents a crucial solution for energy conversion and storage, addressing environmental challenges while meeting rising energy needs. In this study, the fabrication of a novel bifunctional catalyst, copper nickel aluminum spinel (Cu0.5Ni0.5Al2O4) supported on graphitic carbon nitride (GCN), using a solid-state synthesis process is reported. Because of its effective interface design and spinel cubic structure, the Cu0.5Ni0.5Al2O4/GCN nanocomposite, as synthesized, performs exceptionally well in electrochemical energy conversion, such as the oxygen evolution reaction (OER), the hydrogen evolution reaction (HER), and energy storage. In particular, compared to noble metals, Pt/C- and IrO2-based water-splitting cells require higher voltages (1.70 V), while for the Cu0.5Ni0.5Al2O4/GCN nanocomposite, a voltage of 1.49 V is sufficient to generate a current density of 10 mA cm−2 in an alkaline solution. When used as supercapacitor electrode materials, Cu0.5Ni0.5Al2O4/GCN nanocomposites show a specific capacitance of 1290 F g−1 at a current density of 1 A g−1 and maintain a specific capacitance of 609 F g−1 even at a higher current density of 5 A g−1, suggesting exceptional rate performance and charge storage capacity. The electrode’s exceptional capacitive properties were further confirmed through the determination of the roughness factor (Rf), which represents surface heterogeneity and active area enhancement, with a value of 345.5. These distinctive characteristics render the Cu0.5Ni0.5Al2O4/GCN composite a compelling alternative to fossil fuels in the ongoing quest for a viable replacement. Undoubtedly, the creation of the Cu0.5Ni0.5Al2O4/GCN composite represents a significant breakthrough in addressing the energy crisis and environmental concerns. Owing to its unique composition and electrocatalytic characteristics, it is considered a feasible choice in the pursuit of ecologically sustainable alternatives to fossil fuels.
