What are the types of catalysts used in greener syntheses?
There are several types of catalysts that are widely employed in greener synthesis routes:
Homogeneous Catalysts: These are catalysts that exist in the same phase as the reactants, typically in solution. They offer high selectivity and activity but can be difficult to separate from the reaction mixture. Heterogeneous Catalysts: These catalysts are in a different phase than the reactants, often solid catalysts in liquid or gas phase reactions. They are easier to separate and recycle. Biocatalysts: Enzymes and other biological molecules act as catalysts. They are highly selective and operate under mild conditions, making them ideal for green synthesis.
