Titanium Oxide Nanopowder Water Dispersion (TiO2, Anatase, 15 wt%, 5-30 nm)

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Anatase, 15 wt%, 5–30 nm) is a water-based suspension of titanium dioxide nanoparticles in the anatase crystalline form. Here’s a detailed explanation of its characteristics, properties, and uses:

1. Composition:

• Titanium Dioxide (TiO₂):
  • A versatile metal oxide known for its photocatalytic, optical, and chemical stability properties.
• Anatase Phase:
  • The anatase crystalline form is characterized by:
    • High photocatalytic efficiency.
    • Strong UV absorption capabilities.
    • Higher activity compared to the rutile phase.
• Nanoparticles (5–30 nm):
  • The particle size range of 5–30 nanometers provides a high surface area for enhanced reactivity while maintaining good stability.
• 15 wt%:
  • The dispersion contains 15% by weight of TiO₂ nanoparticles, with the remaining 85% being water.
• Water-Based Dispersion:
  • Ensures even distribution of nanoparticles and compatibility with aqueous systems.

2. Key Properties:

• High Photocatalytic Activity:
  • Effective for decomposing organic compounds, pollutants, and microorganisms.
• UV Absorption:
  • Provides robust UV blocking capabilities, suitable for sunscreens and protective coatings.
• Nano-Size Advantage:
  • The 5–30 nm particle size enhances surface area and reactivity while offering flexibility in applications.
• Stable Dispersion:
  • Maintains uniform nanoparticle distribution, preventing settling or aggregation.
• Hydrophilic Nature:
  • Readily disperses in water and integrates into various water-based formulations.

3. Applications:

• Photocatalysis:
  • Used in environmental remediation, such as air and water purification systems, to degrade pollutants and organic matter.
  • Ideal for self-cleaning surfaces on buildings, glass, and textiles.
• UV Protection:
  • Incorporated into sunscreens, cosmetics, and coatings to block harmful UV rays effectively.
• Antibacterial and Antiviral Coatings:
  • Provides antimicrobial properties for medical devices, surfaces, and textiles.
• Energy Applications:
  • Used in dye-sensitized solar cells (DSSCs) and photocatalytic energy systems.
• Coatings and Paints:
  • Improves UV resistance, durability, and self-cleaning properties in industrial and architectural coatings.
• Pigments:
  • Adds brightness and opacity in paints, plastics, and inks.
• Environmental Remediation:
  • Effective in treating wastewater and removing harmful chemicals or microorganisms.

4. Advantages:

• High Reactivity:
  • The anatase phase ensures superior photocatalytic performance compared to other phases.
• Environmentally Friendly:
  • A water-based system avoids harmful organic solvents, making it safer and easier to use.
• Versatile:
  • Suitable for a wide range of industrial, environmental, and cosmetic applications.
• Pre-Dispersed:
  • Ready-to-use formulation reduces preparation time and ensures consistent performance.
• Nano-Enhanced:
  • Small particle size provides better interaction with other materials and surfaces.

5. Handling and Storage:

• Handling:
  • Shake or stir well before use to ensure the nanoparticles are uniformly dispersed.
  • Wear protective gloves and goggles to avoid direct 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 regarded as safe, avoid inhaling mists or prolonged contact with skin or eyes.

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Anatase, 15 wt%, 5–30 nm) is a highly effective material for applications requiring strong photocatalytic activity, UV protection, and environmental remediation. Its anatase phase and nano-size ensure high reactivity and performance in a broad range of industrial, cosmetic, and environmental settings.
