Hexagonal sheets of Co3O4 and Co3O4-Ag for high-performance electrochemical supercapacitors
E-mail:,
Hexagonal sheets of Co3O4 on nickel foam were synthesized by a facile, economical, scalable, and one pot hydrothermal method for supercapacitor studies. The electrical conductivity and catalytic activity were enhanced through the decoration of Co3O4 by silver (Ag) nanoparticles using a simple chemical approach. The hexagonal sheets served as an excellent backbone together with the Ag nanoparticles, which gave the composites a superior specific capacitance of 958 F g-1 and an energy density of 0.203 kWh kg-1. The electrode exhibited excellent cycling stability with a capacitance retention of 104% after the initial 1000 CV cycles with a maximum specific capacitance 996 F g-1.
