MoS /MoO -Nanostructure-Decorated Activated Carbon Cloth for Enhanced Supercapacitor Performance.

MoS /MoO nanostructures were grown on activated carbon cloth through a facile one-step microwave-assisted hydrothermal method. The growth of MoS /MoO on activated carbon cloth creates a unique structure that favors ion intercalation. The conductive activated carbon cloth, MoO , and monoclinic MoO provide fast electron transport, whereas the MoS nanosheets/MoO nanoparticles structure improves the capacitance. As a result, MoS /MoO -nanostructure-decorated activated carbon cloth shows a high specific capacitance of 230 F g at a scan rate of 5 mV s with a low contact resistance of approximately 1.91 Ω. Moreover, the activated carbon cloth acts as a template for the growth of a perpendicular MoS layer, which gives an excellent utilization rate of the active MoS /MoO material. We also demonstrate that the MoS /MoO /activated carbon cloth nanocomposite shows excellent electrochemical stability with retention up to 128 % after 1500 cycles. Finally, we show the use of a microwave-assisted hydrothermal method for the synthesis of the MoS /MoO /activated carbon cloth nanocomposite as an alternative and clean route to improve the kinetics of the intercalation redox reaction.
