MoS2 with a 2D layered structure and high theoretical capacity has been regarded as a promising candidate for anode materials in lithium ion batteries. But its poor cyclic stability and low rate capability hinder its practical applications. Herein, hierarchical MoS2 nanotori consisting of MoS2 nanosheets with an increased interlayer distance were synthesized by a facile hydrothermal reaction for the first time. A possible formation mechanism of the hierarchical MoS2 nanotori is proposed based on the scanning electronic microscopy (SEM) results and the influence of the MoO3 precursor on the morphology of the MoS2 obtained. The hierarchical MoS2 nanotori display superior reversible capacity, good rate capability and improved cyclic performance, which can be attributed to their hierarchical surface, hollow structure feature and increased layer distance. The formation mechanism of hierarchical MoS2 nanotori proposed here should offer a new technique for the design and synthesis of MoS2 with different morphologies using MoO3 as the growth template.
