Abstract
Abstract In this work, Ag anchored ZnSb2O6 nanostructured electrode materials have been prepared by facile ultrasonication assisted chemical reduction approach. The diverse properties of Ag anchored ZnSb2O6 electrode materials were characterized through XRD, FT-IR, FE-SEM, UV visible spectroscopy, PL, XPS and BET analysis. The results suggest that Ag nanoparticles are homogeneously distributed on ZnSb2O6 nanorods. While evaluating as a supercapacitor electrode material, Ag anchored ZnSb2O6 electrode exhibits pseudocapacitance with fast faradaic reactions with the maximum specific capacitance of 165.9 F g−1 at a charge/discharge current density of 1.0 A g−1 with 98.0% initial capacitance retained after 2000 cycles. The superior pseudocapacitive properties of Ag anchored ZnSb2O6 are attributed to its unique structure, large surface area to volume for easy access of electrolyte ions and Ag anchored on ZnSb2O6 nanorod has improved the electrical conductivity of the as-prepared electrode and also provided fast electron transfer kinetics for better electrochemical reactions. The results confirm that Ag anchored ZnSb2O6 are advantageous as potential electrochemical energy storage materials in supercapacitors.
