*CuCo2S4–MoS2 nanocomposite: a novel electrode for high-performance supercapacitors
Our latest achievement involves the successful synthesis of MoS2 incorporated CuCo2S4 nanocomposites using a hydrothermal technique. These ternary transition metal sulfides exhibit tremendous promise in the realm of supercapacitors, offering a unique combination of high conductivity and stability during electrochemical reactions. The thorough investigation of the CuCo2S4–MoS2 nanocomposite revealed its exceptional structural, morphological, elemental, and chemical properties. Notably, the electrochemical capacitor performance showcased remarkable results, with a specific capacitance of 820 F g−1 at a current density of 0.5 A g−1 in the three-electrode system, surpassing the performance of the CuCo2S4 electrode. The incorporation of MoS2 significantly enhanced charge storage capacity, conductivity, and stability of CuCo2S4, leading to the fabrication of an asymmetric supercapacitor. This solid-state device demonstrated outstanding long-term cyclic stability, retaining 89% after 1000 galvanostatic charge-discharge cycles. Moreover, it exhibited a high energy density of 38.22 W h kg−1 at a power density of 400 W kg−1, illuminating a red LED for 170 s—a clear indication of its superiority over conventional Cu-Co based supercapacitors. Join us in exploring the forefront of energy materials research and the limitless potential for innovative applications.
A part form the development of high-performance energy materials, our research at the Energy Materials Lab focuses on addressing the environmental impact of elevated NO2− levels resulting from the improper handling of high nitrogen-content chemicals. Such elevated levels can have severe consequences on the natural ecosystem, contributing to the development of cancer and other fatal diseases in both animals and humans. To mitigate this issue, we have developed a non-enzymatic electrochemical NO2− sensor using a glassy carbon electrode (GCE) modified with Pt nanoparticle (PtNP) coated carboxylated activated jute carbon (PtNP_CAJC/GCE). The carboxylated activated jute carbon material, synthesized through a thermochemical pathway, and the PtNP coating, prepared via ultrasonication, play crucial roles in achieving efficient electron transfer during electrocatalysis. Our electrochemical probe, PtNP_CAJC/GCE, exhibited superior stability, repeatability, and efficacy in the amperometric detection of NO2− in phosphate buffer solution at pH 7.0 under ambient conditions. The two-electron transfer process observed on the surface of the electrocatalyst, with the second electron transfer identified as the rate-determining step, was elucidated through computational cyclic voltammetry simulations based on evaluated kinetic parameters. Furthermore, the probe demonstrated exceptional selectivity over a wide linear range (4.99 μM−4.23 mM) in the presence of common interfering additives. Successful testing in real samples, such as tap water, using an amperometric method underscores the practical applicability of our PtNP_CAJC/GCE probe for monitoring and detecting NO2− levels in aqueous systems, contributing to the broader goal of environmental sustainability.
