Nanomaterials can be used as catalysts, which are used to accelerate certain chemical reactions. Nanomaterials exhibit good surface activity due to their high specific surface area, which is a necessary condition for nanomaterials to become catalysts. In the catalyst industry, nanoparticle catalysts will undoubtedly play an important role. Photocatalyst is an example of nanomaterials in catalysts. Photocatalyst utilizes the quantum size effect of nano TiO2, which enhances its oxidation-reduction ability and performs well as a catalyst.

2. Application in Coatings
The unique surface structure of nanomaterials determines their ability to be added to coatings. These nanocoats with the addition of nanomaterials have excellent performance that ordinary coatings do not have, which greatly improves the performance of traditional coatings. They transform ordinary coatings into nanocomposite coatings, and commonly used nanomaterials in coatings include nano silicon oxide, nano titanium dioxide, nano iron oxide, nano zinc oxide, etc.

3. Application in Medicine
With the increasing importance placed on health, people are paying more and more attention to the medical aspects of daily life. After entering the era of nanomaterials, nanomaterials play an important role in many aspects, including medicine. How to control the better volatilization of drugs has been a problem that the medical community has been studying, and the emergence of nanomaterials has effectively solved this problem, Using nanomaterials to encapsulate drugs into intelligent drugs, these drugs can actively search for tissues or cells that require drug treatment.

4. Application of in other fine chemicals
Nanomaterials also play an important role in other fine chemicals, such as adding nanomaterials to cosmetics, which can play a good role. Adding nanomaterials with strong ultraviolet absorption capabilities such as nano titanium dioxide and nano zinc oxide to cosmetics can provide good help in preventing ultraviolet radiation.
