HYDROTHERMAL SYNTHESIS OF SULFUR NANOWIRES

Аннотация

The hydrothermal synthesis of sulfur nanowires represents a promising approach for the fabrication of one-dimensional nanostructures with potential applications in energy storage, catalysis, and optoelectronics. This study investigated the controlled growth of sulfur nanowires using a hydrothermal method, focusing on the influence of reaction temperature, time, and precursor concentration on the morphology and crystallinity of the resulting nanostructures. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize the synthesized nanowires, revealing high crystallinity and uniform diameters in the range of 50–200 nm. The formation mechanism was discussed in terms of the self-assembly of sulfur chains under hydrothermal conditions. The results demonstrated that optimal synthesis conditions, including a temperature of 160°C and a reaction time of 12 hours, yielded nanowires with high aspect ratios and minimal defects. This work provides a systematic understanding of the hydrothermal synthesis of sulfur nanowires, offering insights into scalable production for functional nanomaterial applications.
