Facile Synthesis of MoS2 Hierarchical Nanostructures as Electrodes for Capacitor with Enhanced Pseudocapacitive Property.

In this work, the 3D porous hierarchical MoS2 nanostructures were prepared via a simple hydrothermal deposition method only utilizing titanium (Ti) mesh as a substrate. The as-synthesized uniform MoS2 flower-like nanostructures were assembled by nanosheets composed of several stacking layers. The curved and rough surface of cylindrical Ti wire was beneficial to assembly of MoS2 nanosheets into hierarchical architectures. Moreover, the electrochemical performance of the as-prepared MoS2 nanostructured electrodes for capacitors was also investigated. The structural advantages lead to a remarkably improved pseudocapacitive property including high capacitance and durable cycling ability. A binder-free electrode composed of MoS2 hierarchical nanostructures grown on the Ti mesh was fabricated through a simple hydrothermal deposition route. The rough and curved surface of Ti mesh is beneficial to the assembly of MoS2 nanosheets. The MoS2-based nanostructured electrode demonstrated greatly enhanced pseudocapacitive property due to its desirable structural merit. [ABSTRACT FROM AUTHOR]
