There are several strategies to increase the number of active sites on a catalyst:
Nanostructuring: Reducing the particle size of a catalyst increases its surface area and exposes more active sites. Doping: Introducing foreign atoms into the catalyst material can create defects and alter the electronic properties, thereby increasing the number of active sites. Support Materials: Dispersing the active catalyst on a high-surface-area support can improve the accessibility of active sites. Surface Treatment: Chemical or physical treatment of the catalyst surface can create additional active sites by modifying the surface structure.
