Interface engineering for enhancing the performance of novel sodium-doped MoS2 nanocomposite: Synthesis and characterization functioning as a high-performance supercapacitor
Abstract
Novel structured Na-doped MoS2 nanosheets were developed in situ on Ni foam through a more accessible two-step hydrothermal technique. Benefiting from the synergistic reactions of the superior capacitance of Na-doped
MoS2 nanosheet, the superior electrical kinetics of Na-doped, and the porous nanostructure of the composites, the
designed Na-doped MoS2 nanosheet composites electrode achieves notable electrochemical activity. The material's
structural properties investigate using an X-ray photoelectron spectroscope analyzer, X-ray powder diffractions, scanning electron microscope, and transmission electron microscope. The electrochemical activity of the designed electrodes was executed using cyclic voltammograms, galvanostatic charge/discharges, and electrochemical impedance
spectroscopy. Compared to the pure MoS2 electrode, the novel architecture Na-doped MoS2 nanosheet deremonstrates
a higher specific capacity of 374.3 C g1
at 1 A g1
. In addition, it achieves notable cycling stability performance and
retains 87.4% capacity over 5,000 long cycles at 3 A g1
. These notable results reveal that the uniquely designed Nadoped MoS2 nanosheet displays superior electrochemical consequences and higher potential as nanomateria
