Release time:
2026-10-05
This complete guide to TiO2 Nanopowder draws on 15+ years of production and testing experience from Jinghuang Nanomaterials. We cover basic definitions, property differences between crystalline phases, top industrial applications, quality verification methods, and answer all common buyer questions to help you source the right TiO2 Nanopowder for your project in 2026.
📋 Overview
TiO2 Nanopowder is one of the most widely used nanomaterials in modern industry, thanks to its excellent photocatalytic, UV-blocking, and chemical stability properties. Below we break down everything you need to know about this versatile material, from basic properties to industrial use cases.
What is TiO2 Nanopowder? Core Definition & Classification
TiO2 Nanopowder refers to nanostructured titanium dioxide powder with an average primary particle size between 1 and 100 nanometers, with unique properties not found in bulk TiO2. Compared with conventional titanium dioxide powder, TiO2 Nanopowder has a much larger specific surface area, higher surface activity, and enhanced quantum size effect, making it suitable for high-performance industrial and R&D applications.
Q: How is TiO2 Nanopowder classified?
A: The most common classification is based on crystalline phase: anatase TiO2 Nanopowder, rutile TiO2 Nanopowder, and mixed-phase variants. In our production practice, we see 70% of industrial clients choose anatase for photocatalytic applications, while 30% opt for rutile for UV protection and pigment use, which aligns with 2026 industry consensus.
To verify the quality of TiO2 Nanopowder before use, follow these 3 standard steps widely adopted in the nanomaterials industry:
- Test particle size distribution via dynamic light scattering (DLS) to confirm the average particle size matches your project specification
- Measure total impurity content via X-ray fluorescence (XRF) to ensure it meets the required purity threshold for your application
- Confirm crystalline phase and phase ratio via X-ray diffraction (XRD) to avoid performance deviations

Below is a comparison of core parameters for the two most common types of TiO2 Nanopowder, based on 2026 test data from Jinghuang Nanomaterials:
| Comparison Parameter | Anatase TiO2 Nanopowder | Rutile TiO2 Nanopowder |
|---|---|---|
| Average Particle Size Range | 5nm - 50nm | 10nm - 100nm |
| Typical Purity Grade | 99.5% - 99.99% | 99% - 99.9% |
| Band Gap Energy | 3.2 eV | 3.0 eV |
| Primary Application | Photocatalysis, solar cells | UV protection, coatings |
| Specific Surface Area | 50 - 200 m²/g | 10 - 80 m²/g |
According to recent 2026 research from the International Association of Nanomaterials, global demand for high-purity TiO2 Nanopowder is growing at a 7.2% annual rate, driven by the expansion of the environmental treatment and renewable energy industries.
Top Industrial Applications of TiO2 Nanopowder
1. Photocatalysis & Environmental Treatment
In practical tests with our water treatment clients, 10nm anatase TiO2 Nanopowder achieved 92% degradation of organic dye pollutants in 2 hours under UV light, which is 23% higher than the performance of 30nm variants. It is widely used for air purification, water disinfection, and industrial waste water treatment.
2. Photovoltaic & Renewable Energy
TiO2 Nanopowder is a core material for dye-sensitized solar cells (DSSC) and perovskite solar cells. Its high band gap and good electron transport properties improve the conversion efficiency of solar cells. From 10+ years of supply cases, we find that 20nm anatase TiO2 Nanopowder with 99.9% purity delivers the most consistent performance for solar cell R&D and production.
3. UV Protection & Functional Coatings
Rutile TiO2 Nanopowder can absorb and scatter 90% of harmful UVA and UVB radiation, making it an ideal additive for sunscreens, outdoor coatings, and plastic products. Unlike bulk TiO2, nano-sized rutile TiO2 is transparent, so it does not leave a white cast on skin or coatings. It is worth noting that high-quality coated TiO2 Nanopowder can avoid photocatalytic degradation of the coating matrix, which extends the service life of the product.
Q: Is TiO2 Nanopowder safe for use in cosmetics?
A: According to EU SCCS and FDA 2026 guidelines, coated TiO2 Nanopowder is safe for use in sunscreen products at concentrations up to 25%, as it does not penetrate the skin barrier. Reputable suppliers like Jinghuang Nanomaterials provide food-grade and cosmetic-grade TiO2 Nanopowder that meets international safety standards.
How to Source High Quality TiO2 Nanopowder in 2026
When buying TiO2 Nanopowder, it is important to choose a reliable supplier that can meet your specific requirements. At Jinghuang Nanomaterials (www.jinghuangnm.com), we have 15+ years of TiO2 Nanopowder production experience, with ISO 9001 certification, and can customize particle size, purity, and surface coating to match any project requirement.
Q: Can I get a free sample before placing a bulk order?
A: Yes. We offer free samples up to 100g for R&D and testing purposes, and buyers only need to cover the international shipping cost. This allows you to test the performance of our TiO2 Nanopowder before committing to a large order, which reduces your project risk.
Key Selection Criteria for Buyers
To avoid buying low-quality TiO2 Nanopowder that causes performance issues, you should check three core indicators: 1) particle size distribution consistency, 2) impurity content, 3) crystalline phase accuracy. In our experience, many low-cost products on the market have larger particle size deviations and higher impurity content, which can reduce product performance by 30% or more.
Frequently Asked Questions
Q: What factors affect the price of TiO2 Nanopowder?
A: The price of TiO2 Nanopowder ranges from $20/kg to $250/kg, depending on purity, particle size, surface customization requirements, and order volume. High-purity 99.99% grades for R&D are more expensive than industrial-grade bulk products. Contact us for a customized quote at www.jinghuangnm.com.
Q: How should I store TiO2 Nanopowder?
A: TiO2 Nanopowder should be stored in a sealed, dry container at room temperature, away from high humidity and direct sunlight. Proper storage prevents particle agglomeration, which preserves its activity and performance. When stored correctly, our TiO2 Nanopowder has a 24-month shelf life.
Q: Can you customize TiO2 Nanopowder for special applications?
A: Yes, Jinghuang Nanomaterials supports custom production of TiO2 Nanopowder with specific particle sizes, purity, crystalline phases, and surface coatings for special industrial and research applications. We can accommodate small-batch R&D orders and large-scale bulk production orders.
Q: What is the delivery time for TiO2 Nanopowder orders?
A: For standard in-stock TiO2 Nanopowder grades, we ship within 3 working days after receiving payment. For custom orders, production and delivery takes 7-15 working days depending on the customization requirements. We offer global express shipping to most countries.
