Abstract

The synthesis of ultralong, low-diameter, and uniform nanowires holds significant promise for integrating multiple devices within a single structure. In this study, a hydrothermal synthesis method was employed to grow ultralong Co-doped SnO₂ nanowires. The reaction conditions, including temperature, concentration of precursors, and the introduction of Co as a dopant, were optimized for producing high-aspect-ratio, crystalline nanowires. These nanowires were then characterized for their structural and electrical properties, and their potential for gas sensing and photocatalytic applications was explored. The results suggest that Co-doped SnO₂ nanowires could play a crucial role in future nanodevice applications.
