| Description | The fascinating features of 2D nanomaterials for various applications have prompted increasing research into single and few-layer metal dichalcogenides nanosheets using improved nanofabrication and characterization techniques. $MoS_{2}$ has recently been intensively examined among layered metal dichalcogenides and other diverse transition metal-based materials, that have previously been studied in various applications. In this research, we report mixed-phase Mn-doped $MoS_{2}$ nanoflowers for supercapacitor performance studies. The confirmation of the successfully prepared Mn-doped $MoS_{2}$ nanoflowers was characterized by XRD, SEM-EDS, RAMAN, and BET research techniques. The mixed-phase of the as-synthesized electrode material was confirmed by the structural changes observed in the XRD and RAMAN studies. The surface area from the BET measurement was calculated to be 46.0628 $m^{2}$/g, and the adsorption average pore size of the electrode material was 11.26607 nm. The electrochemical performance of the Mn-doped $MoS_{2}$ electrode material showed a pseudo-capacitive behavior, with a specific capacitance of 70.37 $Fg^{−1}$, and with a corresponding energy density of 3.14 $Whkg^{−1}$ and a power density of 4346.35 $Wkg^{−1}$. The performance of this metal-doped $MoS_{2}$-based supercapacitor device can be attributed to its mixed phase, which requires further optimization in future works. |
