Enhanced activity of a hydrothermally synthesized mesoporous MoS2 nanostructure for high performance supercapacitor applications

Abstract

In the present work, we have synthesized a mesoporous molybdenum disulfide (MoS₂) nanostructure by a facile hydrothermal route for supercapacitor applications. FE-SEM and TEM images confirmed the mesoporous morphologies of the as-prepared samples. The electrochemical measurements showed that the as-prepared mesoporous MoS₂ electrode delivered maximum capacitances of 376 and 403 F g⁻¹ at a scan rate of 1 mV s⁻¹ in 1 M Na₂SO₄ and KCl electrolyte solutions respectively, which indicated that the mesoporous MoS₂ nanostructure was a suitable electrode material for supercapacitor applications.
