Several examples illustrate the impact of chemical modifications on catalytic performance:
1. Zeolites: By substituting aluminum with other metals, the acidity and thus the catalytic activity of zeolites can be tailored. 2. Metal Catalysts: Doping platinum catalysts with other metals like ruthenium or iridium can enhance their performance in hydrogenation reactions. 3. Enzyme Catalysts: Site-directed mutagenesis can be used to modify specific amino acids in enzymes, improving their efficiency and specificity.
