Abstract

Molybdenum disulfide (MoS₂) is a promising nanomaterial which has been extensively investigated in photo-/electro-catalysis, sensors, and batteries due to its excellent physical/chemical properties. In this manuscript, MoS₂ hierarchical nanotubes with hollow nanostructure are successfully synthesized via a facile hydrothermal method. SEM indicates that such MoS₂ nanotubes have perfect uniformity while TEM demonstrates the hollow structure. Specifically, the ratio of MoS₂ to the randomly produced polysulfide in the synthesized MoS₂ nanotubes is 4.29 which confirms that the synthesized MoS₂ nanotubes have quite high quality. Compared with the previous studies, our MoS₂ nanotubes show superior rate capability and cyclability (127 mAh g⁻¹ at 200 mA g⁻¹ after 100 cycles) in the potassium ion battery. © 2019 Elsevier Inc.
