What Catalysts are Used in Supercritical Fluid Catalysis?
Both homogeneous and heterogeneous catalysts can be employed in SCF catalysis. Common catalysts include: - Metal Complexes: Homogeneous catalysts like transition metal complexes are dissolved in SCFs, facilitating reactions such as hydrogenation and oxidation. - Supported Metal Catalysts: Heterogeneous catalysts, such as platinum or palladium on various supports, are dispersed in the SCF medium to enhance surface interactions. - Acid-Base Catalysts: Solid acids or bases can be used to catalyze reactions like esterification and transesterification in SCFs.
