Abstract

Herein, we report the preparation of Pongam seed shells-derived activated carbon and cobalt oxide (∼2-10 nm) nanocomposite (PSAC/Co₃O₄) by using a general and facile synthesis strategy. The as-synthesized PSAC/Co₃O₄ samples were characterized by a variety of physicochemical techniques. The PSAC/Co₃O₄-modified electrode is employed in two different applications such as high performance nonenzymatic glucose sensor and supercapacitor. Remarkably, the fabricated glucose sensor is exhibited an ultrahigh sensitivity of 34.2 mA mM^-1 cm^-2 with a very low detection limit (21 nM) and long-term durability. The PSAC/Co₃O₄ modified stainless steel electrode possesses an appreciable specific capacitance and remarkable long-term cycling stability. The obtained results suggest the as-synthesized PSAC/Co₃O₄ is more suitable for the nonenzymatic glucose sensor and supercapacitor applications outperforming the related carbon based modified electrodes, rendering practical industrial applications. (Figure Presented).
