Titanium dioxide nanopowder (TiO2) is a white solid or powdered amphoteric oxide with a chemical formula of TiO2 and a molecular weight of about 79.9. It is known for its non-toxicity, opacity, optimal whiteness and brightness, and is currently one of the world's most outstanding white pigments. Among many commonly used white pigments, titanium dioxide has the smallest relative density, and at the same mass, it has the largest surface area and the highest pigment volume. In addition, titanium dioxide has strong adhesion, is not prone to chemical changes, and maintains a permanent snow-white state. Nano-scale titanium dioxide has a small particle size, is easy to disperse, and has high purity and low impurity content.
Through a variety of surface modification techniques, such as silane coupling agent method, its compatibility with the polymer matrix can be enhanced, making it suitable for the needs of different industries. This material is not only environmentally friendly and non-toxic, but also has high stability
Nano titanium dioxide has two main crystalline forms: anatase and rutile. Rutile titanium dioxide is more stable and dense than anatase titanium dioxide, with higher hardness, density, dielectric constant and refractive index, and higher hiding power and tinting power. The reflectivity of anatase titanium dioxide in the short-wave part of visible light is higher than that of rutile titanium dioxide, with a blue hue, and its absorption capacity for ultraviolet rays is lower than that of rutile, and its photocatalytic activity is higher than that of rutile. Under certain conditions, anatase titanium dioxide can be converted into rutile titanium dioxide.
Anatase Titanium Dioxide Nanopowder
It is a high-efficiency photocatalyst with high photocatalytic efficiency. It has large specific surface area, high activity, and catalytic carrier. Under ultraviolet light conditions, it can quickly oxidize and degrade organic matter, converting it into CO2, H2O and inorganic matter, without secondary pollution. Its applications include the following aspects:
Photocatalyst coating: It can be used as a photocatalyst to degrade formaldehyde, benzene, ammonia, TVOC, etc., and purify the air.
Diatom mud: Photocatalyst, formaldehyde removal.
Industrial waste gas, automobile exhaust: It can degrade NOx, CO, SOx and other atmospheric pollutants to reduce emissions.
Catalyst carrier: High activity, photocatalytic properties, used for catalysts and carrier materials.
Wastewater and sewage treatment: Photocatalyst degradation of organic pollutants.
Battery: Lithium battery, solar cell, increase capacity and increase stability.
Ceramic: Antibacterial ceramics, self-cleaning ceramics.
