Abstract

In this work, Bi_3.64Mo_0.36O_6.55 nanoparticles (NPs) were successfully prepared by a facile hydrothermal method and utilized in pseudocapacitor for the first time. Within a redox potential range from −1.0 to 0 V vs. Hg/HgO in a 1 M aqueous KOH solution by cyclic voltammetry (CV), chronopotentiometry (CP) and AC impendence, the specific capacitance could reach 998 F g⁻¹ at 1 A g⁻¹, which is possibly ascribed to the higher Bi content of Bi_3.64Mo_0.36O_6.55 NPs. Furthermore, the Bi_3.64Mo_0.36O_6.55 NP electrode exhibited good cycle stability maintaining over 85 % after 5000 cycles. These results demonstrated Bi_3.64Mo_0.36O_6.55 NPs might be a promising electrode material for pseudocapacitor. [Figure not available: see fulltext.]
