Year: 2024

Type: article

Abstract: This study presents the hydrothermal synthesis of a novel TiO 2 nanotubes/MoSe 2 nanocomposite and investigates its enhanced electrochemical capacitance properties. The composite material was fabricated through a hydrothermal method, embedding MoSe 2 onto TiO 2 nanotubes. The resulting composite, termed Ti/TiO 2 /MoSe 2 , exhibited significantly improved electrochemical capacitance compared to TiO 2 nanotubes alone. The synthesized composite was comprehensively characterized using solid-state physics techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). These analyses provided detailed insights into the structural and chemical composition of the TiO 2 /MoSe 2 nanocomposite. The investigation revealed that the TiO 2 /MoSe 2 nanocomposite displayed superior electrochemical performance, as determined by various electrochemical methods. Notably, the composite exhibited a capacitance approximately 10 times higher than that of pristine TiO 2 nanotubes. These findings underscore the significant enhancement in energy storage capabilities achieved through the hydrothermal synthesis of TiO 2 /MoSe 2 . The observed enhancement in capacitance positions the TiO 2 /MoSe 2 nanocomposite as a promising candidate for high-performance energy storage applications.
