• Pseudocapacitive Behavior of Ag₃PO₄ Nanospheres Prepared by a Sonochemical Process

抄録

Ag₃PO₄ nanospheres with an average size of ～300 nm were synthesized via a sonochemical process. The electrochemical performances of the as-synthesized Ag₃PO₄ nanospheres in aqueous KOH electrolyte with different concentrations were investigated by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The measured cyclic voltammetry curves as well as charge-discharge curves reveal a good pseudocapacitive behavior of Ag₃PO₄ nanospheres. In a 1 M KOH electrolyte at a current density of 0.5 mA cm⁻², the specific capacitance of Ag₃PO₄ nanospheres is obtained to be 832 F g⁻¹. However, Ag₃PO₄ nanospheres exhibit an inferior charge-discharge cycling stability, which could be due to the formation of Ag₂O during the cycling process.
