Abstract: In this work, novel hierarchical Bi₂MoO₆ nanotubes constructed from interconnected nanosheets have been fabricated and investigated as a high-performance electrochemical material. A facile template-engaged strategy has been utilized to controllably synthesize Bi₂MoO₆ nanotubes by a reflux reaction. The nanotubes with a high surface area of 68.96 m(2)/g were constructed of highly ordered ultrathin nanosheets with a thickness of about 5 nm. Benefitting from the structural advantages including ultrathin nanosheets, large exposed surface, and unique three-dimensional tubular structure, the as obtained hierarchical Bi2MoO6 nanotubes exhibit excellent electrochemical performance. The specific capacitance of the hierarchical nanotubes can be up to 171.3 Fg^-1 at a current density of 0.585 Ag^-1 and excellent stability with 92.4% capacitance retention after 1000 cycles, which is much better than that of nanosheets (18.7 Fg^-1 at a current density of 0.585 Ag^-1, 69.5% capacitance retention).
