Lehrinhalt

This lecture introduces two key catalytic strategies for greener chemical synthesis: biocatalysis and electrocatalysis. Both approaches support the goals of green chemistry by improving selectivity, reducing energy demand, minimizing waste, and enabling the use of renewable resources.

The biocatalysis part covers the use of enzymes and whole cells as catalysts in chemical transformations. Students learn how biocatalysts enable highly selective reactions under mild conditions, often in aqueous media, and how they can replace hazardous reagents or multi-step synthetic routes. Examples include the enzymatric production of fine chemicals, pharmaceuticals, and bio-based materials.

The electrocatalysis part focuses on chemical reactions driven by electricity. Topics include electrode materials, redox processes, and electrochemical syntheses. The lecture highlights how electrocatalysis can reduce the need for stoichiometric oxidants or reductants and contribute to sustainable energy conversion and storage.

By comparing biological and electrochemical catalysis, students gain an understanding of how catalyst design, reaction conditions, and process integration can make chemical production cleaner, safer, and more resource-efficient.
