Synthesis and Pseudocapacitve Properties of Tungsten Oxide Nanorods

Abstract:

Tungsten oxide (WO₃) nanorods were fabricated and evaluated as negative electrode materials for supercapacitors. The influence of the concentration of sodium chloride and pH value of the synthesis solution were investigated. The pH value of solution and sodium chloride play important roles in the formation of uniform dispersed nanorods of WO₃. Cyclic voltammetry and chronopotentiometry results show that nanorods WO₃ film exhibit advanced pseudocapacitive performance over a negative potential range of − 0.6 V to 0.2 V vs. SCE in 1M H₂SO₄ with the high specific capacitance of 114 F g^-1, compared to that of the bulk WO₃ electrode materials.
