Homogeneous catalysis involves a catalyst that is in the same phase as the reactants, typically in a liquid solution. This allows for better interaction between the catalyst and the reactants, often leading to increased reaction rates and selectivity. Common examples include reactions in organic chemistry where metal complexes, such as those containing platinum or palladium, facilitate transformations.
In homogeneous catalysis, the catalyst can be easily mixed with the reactants, making it simpler to control reaction conditions. However, separating the catalyst from the products can be challenging. This method is widely used in industrial processes, including the production of pharmaceuticals and fine chemicals.
