Why are Core-Shell Structures Important in Catalysis?
Core-shell structures are crucial in catalysis for several reasons:
Enhanced Activity: The core material, often a metal or metal oxide, provides the primary active sites for the catalytic reaction. Increased Stability: The shell can protect the core from sintering, leaching, or deactivation during the reaction. Selective Permeability: The shell can be engineered to allow specific reactants to pass through while blocking others, thereby enhancing selectivity. Improved Dispersion: The shell can help to disperse the core material more evenly, increasing the number of active sites available for the reaction.
