Titanium Oxide Nanopowder Water Dispersion (TiO₂, Anatase, 15 wt%, 30–50 nm) is a water-based suspension of titanium dioxide nanoparticles in the anatase crystalline phase. This particular formulation contains nanoparticles with a size range of 30–50 nanometers, making it suitable for various industrial, environmental, and cosmetic applications. Below is a detailed breakdown of its properties, applications, and advantages:
1. Composition:
- Titanium Dioxide (TiO₂):
- A widely used metal oxide known for its exceptional optical, chemical, and photocatalytic properties.
- Anatase Phase:
- Anatase TiO₂ has the highest photocatalytic activity among the TiO₂ phases and is often preferred for its UV-blocking and pollution-degradation abilities.
- Nanoparticles (30–50 nm):
- This particle size range provides a larger surface area compared to larger particles, enhancing reactivity while maintaining stability in dispersion.
- 15 wt%:
- The dispersion contains 15% by weight of TiO₂ nanoparticles, with the rest being water, making it a concentrated solution.
- Water-Based Dispersion:
- The nanoparticles are uniformly suspended in water, making it easy to handle and apply in aqueous systems.
2. Key Properties:
- High Photocatalytic Activity:
- Anatase TiO₂ is highly effective in promoting reactions that decompose organic pollutants, microorganisms, and harmful chemicals when exposed to UV light.
- UV Absorption:
- Excellent at blocking harmful UV rays, making it ideal for applications requiring UV shielding.
- Moderate Particle Size:
- The 30–50 nm size range strikes a balance between high surface area for reactivity and stability in dispersion. Larger particles provide better handling in coatings and systems.
- Stable Dispersion:
- Prevents aggregation of particles, ensuring that the dispersion remains effective and uniform over time.
- Hydrophilic:
- The hydrophilic nature of the dispersion ensures good compatibility with water-based formulations.
3. Applications:
- Photocatalysis:
- Utilized in air and water purification systems, where the high photocatalytic activity of anatase TiO₂ helps break down pollutants and organic matter.
- Can also be applied to self-cleaning surfaces, such as glass, tiles, and buildings, by enabling degradation of dirt and bacteria when exposed to sunlight.
- UV Protection:
- Incorporated in sunscreens, cosmetics, and coatings to block UV radiation and prevent skin damage.
- Antibacterial and Antiviral Coatings:
- Applied to medical devices, textiles, and surfaces to provide antimicrobial properties, reducing the growth of harmful bacteria and viruses.
- Energy Applications:
- Used in photocatalytic energy systems, such as dye-sensitized solar cells (DSSCs), to enhance energy efficiency.
- Coatings and Paints:
- Provides UV resistance and enhances the durability and weatherability of paints, coatings, and surface treatments.
- Environmental Remediation:
- Employed in wastewater treatment and the degradation of harmful chemicals and pollutants.
- Pigments:
- Adds opacity and brightness to paints, plastics, and inks.
4. Advantages:
- Enhanced Photocatalytic Activity:
- Anatase phase TiO₂ offers superior photocatalytic performance, making it effective in pollution control and self-cleaning applications.
- Good Stability:
- The dispersion remains stable over time, ensuring consistent performance without settling or agglomeration of particles.
- Environmentally Friendly:
- Water-based dispersion avoids harmful organic solvents, reducing the environmental impact and making it safer for users.
- High Reactivity:
- The smaller particle size (30–50 nm) provides a higher surface area for reactions, making it more effective in catalytic and UV-blocking applications.
- Ready-to-Use:
- The dispersion is pre-dispersed and can be directly integrated into various formulations without the need for additional processing.
5. Handling and Storage:
- Handling:
- Shake or stir thoroughly before use to ensure uniform dispersion of nanoparticles.
- Use gloves and goggles to avoid direct contact with the dispersion, particularly when working in concentrated forms.
- Storage:
- Store in a cool, dry place away from direct sunlight and high temperatures.
- Do not freeze, as it could destabilize the dispersion.
- Safety:
- While TiO₂ is generally safe, avoid inhaling the mist or prolonged exposure to the dispersion.
