Synthesis of 2-D nanostructured BiVO4:Ag hybrid as an efficient electrode material for supercapacitors

Abstract

2-D BiVO4 nanosheets with monoclinic phase were synthesized at room temperature, and incorporated with Ag to form BiVO4:Ag hybrid materials. The experiments demonstrated that doping Ag has largely increased the electrochemical performances of supercapacitor. Furthermore, the specific capacitance can reach up to 109Fg–1 at 1Ag–1 (the undoped one is of 27Fg–1); energy density has enhanced to 15.2Whkg–1 compared with the pristine one without Ag (3.8Whkg–1). Therefore, doping Ag into bismuth-based compound provides us an alternative approach for the synthesis of 2-D nanostructured hybrid as an efficient electrode material for supercapacitors
