Silicon is pivotal in catalysis for several reasons. Firstly, its ability to form stable bonds with oxygen results in robust and durable catalytic materials. Secondly, silicon-based compounds, such as silica and organosilicon compounds, exhibit high surface areas and tunable pore structures, crucial for enhancing catalytic activity. Lastly, silicon's chemical versatility allows for functionalization, enabling the design of catalysts with specific properties tailored for particular reactions.
