Two dimensional (2D) MoS₂ nanosheet has been successfully grown on Activated Carbon Clothes (ACC) by facile method, microwave-assisted hydrothermal at a shorter time. We have investigated the growth mechanism at different time reactions and their performance as electrode material of supercapacitor. Scanning electron microscopy (SEM) confirmed that time reaction controls the morphology and growth orientation of MoS₂. On the other hand, it was found from the X-Ray Photoelectron Spectroscopy (XPS) that the additional phase which is MoO₃ was formed during the reaction. This phase contributed to the performance by giving an additional pseudocapacitance. Furthermore, the intimate contact between MoS₂ and ACC favor for fast electron transport during the charge and discharge. As a result, MoS₂/ACC composite shows an excellent performance with specific capacitance of 230 F g^-1 at a scan rate of 5 mV s^-1 in 1M H₂SO₄  and high energy density of 79.9 W h kg^-1 at high power density of 1044 W kg^-1. Noteworthy, by growing MoS₂ on ACC, the specific capacitance of MoS₂ is 913.7 F g^-1 which is the highest that ever been reported. Furthermore, this free-standing material is a promising material for a flexible supercapacitor.
