Sulfur-Doped Multi-Walled Carbon Nanotubes (S-MWCNTs)

Product Overview
Sulfur-doped multi-walled carbon nanotubes (S-MWCNTs) are multi-walled carbon nanotubes that have been chemically modified by introducing sulfur atoms into their structure. The incorporation of sulfur creates new chemical active sites within the carbon nanotube structure, altering their physical, chemical, and electrical properties. These changes enhance the performance of sulfur-doped carbon nanotubes in catalysis, energy storage, and environmental protection applications. S-MWCNTs exhibit excellent performance in batteries, supercapacitors, and catalytic reactions, improving energy storage efficiency, catalytic activity, and biocompatibility.

Key Features

• Enhanced Catalytic Activity: The sulfur doping introduces active sites on the surface of the carbon nanotubes, improving their catalytic activity in reactions.
• Tunable Optical Properties: Sulfur doping can adjust the optical absorption and emission characteristics of carbon nanotubes, making them suitable for optoelectronic applications.
• Improved Biocompatibility: Compared to undoped carbon nanotubes, sulfur-doped ones exhibit improved biocompatibility, making them more suitable for biomedical applications.
• Enhanced Gas Adsorption: Sulfur doping increases the gas adsorption capability of the carbon nanotubes for gases like CO₂ and H₂S, showing potential in environmental protection applications.

Applications

• Energy: Used as materials for batteries and supercapacitor electrodes, improving energy storage and conversion efficiency.
• Catalysis: Serves as a catalyst or catalyst support, increasing catalytic activity and selectivity, with widespread applications in the chemical industry.
• Biomedical: Applied in drug delivery systems and biosensors, improving drug delivery efficiency and biological detection sensitivity.
• Environmental Protection: Used in gas adsorption and separation technologies, helping address air and water pollution issues.
