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.
