One dimensional WS2 nanoarchitectures coupled with g-C3N4 anchored rGO sheets for high performance electrochemical energy storage applications
Original language description
Herein, tungsten sulfide (WS2) nanorods (NRs) with g-C3N4 and rGO were synthesized in order to design a costeffective electrode material (WS2/g-C3N4/rGO) for advanced electrochemical relevance. The rGO nanosheets along with a metal free g-C3N4 with graphene like layered structure improved the electrical conductivity and electro-active surface area of the ternary nanocomposite. The structure, morphology and surface area of asprepared electrodes were comprehensively studied via XRD, FTIR, EDX, FESEM and BET analyses. As projected, surface assisted WS2 NRs were smooth, uniform, interconnected and well aligned with an average diameter of 24.78 nm diameter. The ternary nanocomposite (WS2/g-C3N4/rGO) delivered highest specific capacitance 1383.33F/g at a scan rate 5 mV/s. The GCD plots proposed large discharge time for WS2/g-C3N4/ rGO nanocomposite (918 sec) with high specific capacitance of 850 mAh/g at 1 A/g as compared to WS2/g-C3N4 (623 sec) with specific capacitance 578 mAh/g. The energy density and power density of WS2/g-C3N4/rGO nanocomposite were calculated to be 35.41 Wh/Kg and 139.15 W/Kg, respectively. The noteworthy electrochemical efficiency of WS2/g-C3N4/rGO nanocomposite noticed from CV and GCD results are attributed to the enhanced surface area, porous nanoarchitecture, and nanocomposite composition. The ternary nanocomposite electrode (WS2/g-C3N4/rGO) also showed the fastest ion diffusion and good capacitive retention. In conclusion, our prepared nanocomposite electrode material (WS2/g-C3N4/rGO) exhibits good electrochemical performance and can serve as a better option in the field of energy storage devices.
