Activated alumina (Activated Alumina) is a material widely used in catalyst supports. Due to its large specific surface area and uniform pore structure, it can be used in adsorbents, desiccants and catalyst supports. This article will discuss the application of activated alumina in catalyst supports.

First, it is worth noting that the function of a catalyst support is to provide surface area and pore structure for chemical reactions to occur. Activated alumina has a large surface area and uniform pore structure, so it is a good catalyst carrier. The pore structure of activated alumina is conducive to the diffusion of reactant molecules and the dispersion of catalysts, thereby improving the rate and efficiency of the reaction.

Second, the surface properties of activated alumina can also affect the activity and selectivity of catalysts. For example, surface hydroxyl (-OH) and acidic sites can act as catalysts in certain reactions. Meanwhile, the hydrophilic surface can enhance the adsorption and transformation of water-soluble reactants. Therefore, by adjusting the surface chemistry of activated alumina, the activity and selectivity of the catalyst can be tuned.

Finally, activated alumina can also be used to immobilize the catalyst, making it more stable and reusable. By processing the catalyst into small balls or shapes together with the activated alumina carrier, the violent movement and aggregation of the catalyst particles can be effectively avoided, thereby prolonging the service life of the catalyst and improving its catalytic efficiency.

In summary, activated alumina is a widely used material for catalyst supports. It plays a very important role in improving the rate and efficiency of catalytic reactions, adjusting the activity and selectivity of catalysts, and improving the stability and reusability of catalysts. In addition, the preparation process of activated alumina is relatively simple and controllable, and has certain sustainability.
