How Do Core Shell Structures Improve Catalytic Performance?
Core shell structures improve catalytic performance through several mechanisms:
Enhanced Surface Area: The shell can provide a high surface area for catalytic reactions, increasing the effective catalytic sites. Electronic Effects: The interaction between the core and shell materials can modify the electronic properties of the active sites, leading to improved reactivity. Stability and Durability: The shell can protect the core from harsh reaction conditions, reducing degradation and extending the catalyst life. Selective Permeability: The shell can act as a selective barrier, allowing specific reactants to reach the core while blocking others, thus enhancing selectivity.
