Titanium Oxide Nanopowder Water Dispersion (TiO₂, Anatase, 40 wt%, 30–50 nm) is a concentrated aqueous suspension of titanium dioxide nanoparticles, specifically in the anatase crystalline form. This dispersion has 40 wt% titanium dioxide, meaning it contains a high concentration of TiO₂ nanoparticles suspended in water. The particle size range is between 30 and 50 nanometers, which provides a balance between high reactivity and stability in water-based systems. Here’s a detailed breakdown of its features:
1. Composition:
- Titanium Dioxide (TiO₂):
- A well-known material with high photocatalytic, optical, and chemical properties. It’s commonly used in environmental and industrial applications.
- Anatase Phase:
- The anatase form of TiO₂ is characterized by:
- Superior Photocatalytic Activity: It’s more reactive under UV light than other forms like rutile.
- UV Absorption: The anatase phase absorbs UV light effectively, making it ideal for UV-blocking applications.
- The anatase form of TiO₂ is characterized by:
- Nanoparticles (30–50 nm):
- The size of the nanoparticles (between 30 and 50 nanometers) gives them a high surface area, which enhances photocatalytic activity while ensuring the dispersion remains stable.
- 40 wt% Concentration:
- The formulation contains 40% by weight of TiO₂ nanoparticles, making it a highly concentrated dispersion, ideal for applications requiring a high dosage of titanium dioxide.
- Water-Based Dispersion:
- The TiO₂ nanoparticles are suspended in water, making the dispersion easy to handle, environmentally friendly, and compatible with water-based systems.
2. Key Properties:
- High Photocatalytic Efficiency:
- The anatase phase provides high photocatalytic activity, making it ideal for environmental applications such as pollution degradation, self-cleaning surfaces, and water purification.
- Strong UV Absorption:
- TiO₂ in the anatase form effectively absorbs and blocks UV radiation, which can be used for UV protection in various coatings and cosmetic formulations.
- Concentrated Formulation:
- The 40 wt% concentration ensures a higher loading of TiO₂, making the dispersion effective in high-performance applications.
- Nano-Size Benefits:
- The small nanoparticle size (30–50 nm) maximizes the surface area for more effective photocatalytic reactions and UV absorption.
- Hydrophilic and Stable:
- Being water-based, the dispersion integrates well into aqueous systems and remains stable over time without particle aggregation.
3. Applications:
- Photocatalysis:
- Environmental Remediation: Used in air and water purification systems, the anatase TiO₂ nanoparticles break down pollutants, harmful chemicals, and organic compounds under UV light.
- Self-Cleaning Surfaces: Ideal for use on surfaces such as glass, tiles, and building materials, where it can degrade organic dirt and bacteria when exposed to sunlight.
- UV Protection:
- Sunscreens and Cosmetics: Effective in blocking harmful UV rays to protect the skin from sun damage.
- Coatings: Used in industrial, automotive, and architectural coatings to provide UV resistance and extend the life of the material.
- Antibacterial Coatings:
- Provides antimicrobial properties for medical devices, textiles, and surfaces by degrading bacteria and viruses through photocatalysis.
- Energy Applications:
- Photocatalytic Solar Cells: Used in dye-sensitized solar cells (DSSCs) and other photocatalytic energy systems for improved energy harvesting.
- Coatings and Paints:
- Enhances the performance of paints and coatings by improving durability, UV stability, and self-cleaning properties.
- Pigments:
- The high concentration of TiO₂ gives added opacity, brightness, and whiteness to paints, plastics, and other colored products.
4. Advantages:
- High Photocatalytic Activity:
- The anatase phase offers superior performance for photocatalytic applications, especially under UV light.
- High Concentration:
- The 40 wt% TiO₂ provides more active material in a smaller volume, which is ideal for high-performance applications requiring high TiO₂ content.
- Stable Dispersion:
- Ensures consistent performance and prevents aggregation of nanoparticles over time.
- Versatile:
- Suitable for a wide range of applications, from environmental cleanup to cosmetics and coatings.
- Eco-Friendly:
- The water-based formulation makes it safer and more environmentally friendly compared to solvent-based alternatives.
5. Handling and Storage:
- Handling:
- Shake or stir thoroughly before use to ensure uniform dispersion of nanoparticles.
- Use protective gear such as gloves and goggles to avoid direct contact with the dispersion.
- Storage:
- Store in a cool, dry place, away from direct sunlight and heat to maintain the stability of the dispersion.
- Do not freeze, as freezing could destabilize the nanoparticle dispersion.
- Safety:
- Although TiO₂ is considered safe for most uses, avoid inhaling mist or dust. Use in a well-ventilated area.
