There are several methods to incorporate sulfur into nanomaterials, including: 1. Chemical Vapor Deposition (CVD): A process where sulfur-containing gases react with the nanomaterial substrate at high temperatures. 2. Hydrothermal Methods: Utilizing high-pressure and high-temperature aqueous solutions to facilitate the doping process. 3. Solid-State Reactions: Direct mixing and heating of sulfur with the nanomaterial. 4. Solution-Based Methods: Involves the use of sulfur-containing precursors in a liquid medium, followed by various chemical reactions to achieve doping.
