Facile Synthesis of Flowerlike Bi₂MoO₆ Hollow Microspheres for High-Performance Supercapacitors

Abstract

Here,\nwe synthesize the flowerlike bismuth molybdate (Bi₂MoO₆) hollow microspheres via a facile hydrothermal method. Morphology\ncharacterization suggests that this structure possesses numerous mesopores\nas well as high specific surface area. When we use the as-synthesized\nBi₂MoO₆ as the supercapacitor electrode material,\nit shows a high specific capacitance (182 F g^–1 at\ncurrent densities of 1 A g^–1) as well as excellent\nrate property (retaining 80% of the capacitance at a current density\nof 5 A g^–1) and cyclic stability. Therefore, we\ncan take into account the characteristics of a hollow sphere and its\noutstanding performance when we design and synthesis electrode materials\nfor future energy storage systems.
