Titanium Oxide Nanopowder Water Dispersion (TiO2, Anatase, 15 wt%, 5-15 nm)

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Anatase, 15 wt%, 5–15 nm) is a water-based suspension of titanium dioxide nanoparticles in the anatase crystalline phase. Here’s a detailed explanation:

1. Composition:

• Titanium Dioxide (TiO₂):
  • A highly versatile material known for its photocatalytic, optical, and chemical properties.
• Anatase Phase:
  • The anatase crystalline form is characterized by:
    • High photocatalytic activity.
    • Strong UV absorption and light scattering.
    • A lower density compared to the rutile phase.
• Nanoparticles (5–15 nm):
  • Ultra-small particles with a size range of 5–15 nanometers, providing a high surface area for enhanced reactivity.
• 15 wt%:
  • The dispersion contains 15% by weight of TiO₂ nanoparticles, with water making up the remaining 85%.
• Water-Based Dispersion:
  • Uniformly dispersed nanoparticles in water for ease of handling and application.

2. Key Properties:

• High Photocatalytic Activity:
  • Effective in breaking down organic compounds, pollutants, and harmful microorganisms.
• UV Absorption:
  • Provides strong UV blocking, making it suitable for sunscreens and protective coatings.
• Nano-Size Benefits:
  • The 5–15 nm particle size ensures a large surface area for reactions.
• Stable Dispersion:
  • Prevents nanoparticle aggregation, ensuring consistent application and performance.
• Hydrophilic Surface:
  • Integrates well into water-based systems and formulations.

3. Applications:

• Photocatalysis:
  • Used in air and water purification systems for breaking down pollutants.
  • Effective in self-cleaning surfaces for buildings, glass, and textiles.
• UV Protection:
  • Incorporated into sunscreens, cosmetics, and coatings to block harmful UV rays.
• Antibacterial Coatings:
  • Provides antimicrobial activity for medical devices, surfaces, and textiles.
• Energy Applications:
  • Utilized in dye-sensitized solar cells (DSSCs) and photocatalytic energy harvesting systems.
• Coatings and Paints:
  • Enhances durability, UV resistance, and self-cleaning properties.
• Pigments:
  • Adds opacity and brightness to paints, plastics, and inks.
• Environmental Remediation:
  • Used for wastewater treatment and pollutant degradation.

4. Advantages:

• High Reactivity:
  • The anatase phase maximizes photocatalytic performance.
• Environmentally Friendly:
  • Water-based dispersion avoids hazardous solvents and is easy to handle.
• Versatility:
  • Suitable for a broad range of industrial, cosmetic, and environmental applications.
• Nano-Enhanced:
  • Small particle size improves surface activity and reactivity.
• Pre-Dispersed:
  • Ready-to-use formulation simplifies application processes.

5. Handling and Storage:

• Handling:
  • Shake or stir well before use to ensure uniform distribution of nanoparticles.
  • Use protective equipment (gloves, goggles) to avoid contact with the dispersion.
• Storage:
  • Store in a cool, dry place, away from direct sunlight and temperature extremes.
  • Avoid freezing or overheating, as these can destabilize the dispersion.
• Safety:
  • While TiO₂ is generally considered safe, avoid inhalation of mist and prolonged skin exposure.
