Alumina is a widely used material in catalysis due to its high surface area, thermal stability, and mechanical strength. However, its natural properties may not always be optimal for specific reactions. Modifying alumina can tailor its characteristics to: - Increase surface area and porosity for better dispersion of active catalytic sites. - Enhance acidic or basic properties to facilitate specific reactions. - Improve thermal stability for high-temperature applications. - Introduce active sites by doping with metals like platinum, nickel, or copper.
