摘要：

Nanoparticle-featured MoS2 and WS2 have been synthesized using a facile one-step hydrothermal approach and their application as electroactive materials for high-performance supercapacitors has been investigated. The electrochemical results of the MoS2 electrode exhibit a higher specific capacitance (C-s) of 1531.2 F g(-1) at 5 mA cm(-2) with good cycling stability (up to 81.6% retention over 3000 cycles). The WS2 electrode delivers a high C-s of 1439.5 F g(-1) at 5 mA cm(-2) and excellent cycling stability with 77.4% retention after 3000 cycles. The outstanding performance of the MoS2 and WS2 electrodes indicates their potential in next-generation high-performance supercapacitor applications.
