Designing electrodes made of multicomponent with multiscale nanostructures serves as a footpath to accelerate the growth and practical applicability of supercapacitors and non-enzymatic glucose sensors. FeCo2S4@Carbyne is prepared by a deposition followed by a solvothermal process onto the nickel foam (substrate). The substrate acts as a conductive bridge providing more active sites, enhancing the charge transport and structural stability of FeCo2S4@Carbyne nanohybrid. Accounting for the above said advantages, the prepared nanohybrid results in an output of 2403.3 F g−1 at 1 A g−1. In addition, the assembled device generates 51.5 Wh kg−1 (energy density) at 0.84 KW kg−1 (power density). Furthermore, the fabricated FeCo2S4@Carbyne non-enzymatic sensor exhibits a limit of detection of about 0.057 mM with a sensitivity of about 157 µA mM−1cm−2. As a result, this work provides insight to develop metal sulphide complexes for multifunctional applications.
