ABSTRACT Aluminum oxide nanoparticles/activated carbon (Al 2 O 3 NPs/AC) nanocomposite were synthesized using an optimized sol–gel synthesis method. Various characterization techniques, including x‐ray, field emission scanning electron microscopy (FE‐SEM), Fourier transform infrared (FTIR), UV–visible spectroscopy and cyclic voltammetry, employed electrochemical properties of the prepared samples. X‐ray diffraction (XRD) analysis revealed higher crystal plane intensities in Al NPs compared to /AC nanocomposites. The average crystallite size was determined be 32 nm for 20 FE‐SEM showcased agglomeration NPs, while composite exhibited agglomerated embedded It found that band gaps 5.5 5.6 eV, respectively. Electrochemical through voltammetry demonstrated specific capacitance nanocomposites six times than NPs. This comprehensive investigation provides valuable insights into enhanced performance nanocomposites, suggesting its potential application energy storage devices.
