What are the benefits of aluminum-based ozone destruction catalysts?

Aluminum oxide is a common inorganic compound. Its chemical formula is Al2O3. It is a high hardness compound. It has many excellent properties, excellent adhesion, high strength, and high temperature resistance.

Let’s take a look at the physical structure of aluminum oxide. The crystal structure of alumina is a hexagonal closest-packed structure, consisting of closely packed hexagonal layers composed of oxygen ions and hexagonal layers composed of aluminum ions alternately stacked. This structure gives alumina high hardness and thermal stability, making it excellent in adhesion,

The surface properties of alumina play a vital role in its adhesion. Since there are a large number of hydroxyl (-OH) and oxygen vacancies on the surface of alumina, these active sites have an important impact on the interaction with other substances. For example, in a water environment, the hydroxyl groups on the surface of aluminum oxide can form hydrogen bonds, thereby forming strong adsorption with water molecules. This adsorption can increase the contact area between aluminum oxide and other substances, thereby improving adhesion.

Therefore, the benefits brought by aluminum-based ozone decomposition catalysts are obvious and have the following characteristics.

(1) High mechanical strength. The physical structure of alumina gives it high mechanical strength, which improves the strength of the ozone decomposition catalyst and makes it less likely to break under actual working conditions.

(2) High hardness. The Mohs hardness of alumina is 9, which greatly improves the wear resistance of the ozone decomposition catalyst.

(3) Larger specific surface area. Activated alumina is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required for catalysis and is widely used as a catalyst and catalyst carrier for chemical reactions.

(4) High temperature resistance. Compared with carbon-based ozone decomposition catalysts, under high concentration and high temperature working conditions, carbon-based ozone decomposition catalysts may burn and cause safety accidents, while aluminum-based ozone decomposition catalysts can withstand high temperatures and will not burn, making them more reliable. Safety.

In summary, aluminum-based ozone decomposition catalysts have more excellent properties than other catalysts. In practical applications, more complex working conditions can be faced
