Investigating the potential use of a ZrO2-supported MoS2-based nanocomposite as the electrochemical effectuation electrode for supercapacitor technology
摘要
Hydrothermal and wet chemical approaches were effectively used to create MoS2/ZrO2 nanocomposites in different weight ratios: MZ-(1:1), MZ-(3:7), and MZ-(7:3). The synthesized nanocomposite having a ratio of (1:1) which shows an enhanced level of crystallinity, according to the XRD experimental data. Owing to its distinct surface characteristics along with synergistic effect between Mo+4 and Zr+4 ions, MoS2/ZrO2 exhibits an enhanced specific capacitance of 230 F g⁻1 at a current density of 1 A g⁻1. MoS2-based zirconium oxide electrode (cathode) and activated carbon (AC) being anode in the construction of a hybrid supercapacitor (ASC). With a 1.6 V potential difference, the ASC operated successfully. MZ-(1:1) //KOH//AC ASC generated an energy density of 46.2 Wh kg⁻1 at a power density of 795 W kg⁻1, which is impressive to contend with present sulfide and oxide-based electrodes. MZ-(1:1) ASCs showed a cyclic performance of 85% at 3 A g⁻1 under a potential of (− 0.8 - 0.8) V across 7000 continuous GCD cycles. The produced nanocomposite having a ratio of (1:1) is fit for supercapacitor applications, according to the results.
