Product Overview

Hiyka's SO3H-Modified Carbon Nanotubes represent a significant advancement in nanomaterial engineering, offering a tailored solution for applications requiring high dispersion, chemical reactivity, and acidic functionality. By attaching sulfonic acid (SO3H) groups to the surface of carbon nanotubes, we have enhanced their solubility in aqueous and polar solvents and introduced strong acidic sites, making them ideal for catalysis, energy storage solutions, and environmental applications. Our SO3H-modified CNTs are designed to meet the needs of both research and industry, facilitating innovation in material science and technology.

Key factor

  • Enhanced Dispersion: The introduction of sulfonic acid groups significantly improves the dispersion of CNTs in water and polar solvents, enabling easier processing and application.
  • Increased Chemical Reactivity: SO3H groups increase the surface reactivity of CNTs, allowing for further chemical modifications and the introduction of additional functional groups.
  • Acidic Functionality: Provides acidic sites for catalytic reactions, making them suitable for use in acid-catalyzed processes and as solid acid catalysts.
  • High Conductivity: Maintains the intrinsic electrical conductivity of carbon nanotubes, suitable for applications in energy storage and conductive materials.
  • Environmental Applications: The enhanced reactivity and dispersion make these CNTs ideal for water treatment, pollutant adsorption, and remediation technologies.
