What are the Applications of Porphyrins in Catalysis?
Porphyrins are employed in numerous catalytic processes. Here are some key applications:
Oxidation reactions: Metalloporphyrins mimic the activity of heme enzymes, catalyzing the oxidation of organic substrates. For instance, iron porphyrins are used in the oxidation of alkanes and alkenes. Photocatalysis: Porphyrins exhibit strong absorption in the visible region, making them suitable for light-driven catalytic processes. They are used in solar energy conversion and environmental remediation. Electrocatalysis: Porphyrins are employed in the electrochemical reduction of CO2 to value-added chemicals and the reduction of O2 in fuel cells. Hydrogen production: Porphyrin-based catalysts are utilized in the production of hydrogen via water splitting, contributing to the development of sustainable energy sources.
