Monometallic catalysts are a class of catalysts that consist of a single metal element. These catalysts are widely used in various industrial processes due to their high efficiency and selectivity. The choice of metal depends on the specific reaction being catalyzed. For example, platinum is commonly used in catalytic converters for automobiles, where it facilitates the conversion of harmful pollutants into less harmful substances. Similarly, palladium is employed in the hydrogenation of alkenes and the synthesis of pharmaceuticals. Nickel catalysts are used in the hydrogenation of aromatics and the production of nylon. The activity and selectivity of monometallic catalysts can be influenced by factors such as the metal's electronic structure, surface area, and the presence of promoters or supports. Despite their advantages, monometallic catalysts may suffer from limitations such as sensitivity to poisoning by certain compounds and the potential for deactivation over time. In recent years, there has been growing interest in the development of more robust and selective monometallic catalysts to address these challenges.
