Some common biomimetic catalysts include: - [Metalloporphyrins](href=""): Mimic the heme group in hemoglobin and are used for oxygenation reactions. - [Metal-Organic Frameworks (MOFs)](href=""): These are porous materials that can incorporate metal ions mimicking the active sites of enzymes. - [Mimics of Metalloenzymes](href=""): These catalysts replicate the active sites of enzymes like nitrogenase and hydrogenase for nitrogen fixation and hydrogen production.
