Abstract

MoS₂ has excellent properties but low conductivity, limiting its use in supercapacitors. Carbon’s high conductivity and stability enhance MoS₂’s electrochemical performance and cycling stability. This study prepared MoS₂/C composites via a one-step hydrothermal method, exploring the effects of solvents and carbon content. Deionized water as a solvent resulted in composites with large specific surface areas and good electrochemical properties. Increasing carbon content improved electrochemical performance, peaking at a glucose content of 0.28 mmol, achieving a specific capacitance of 202.6 F/g. However, excessive carbon content led to decreased performance.
