What are some examples of greener synthesis routes?
Here are a few examples of greener synthesis routes facilitated by catalysis:
Asymmetric Catalysis: This involves using chiral catalysts to produce enantiomerically pure products, which is crucial in the pharmaceutical industry. It reduces the need for extensive separation processes. Hydrogenation Reactions: Using catalysts like palladium, nickel, or rhodium, hydrogenation can be conducted at lower temperatures and pressures, reducing energy consumption. Photocatalysis: Utilizing light to activate catalysts, photocatalysis can drive chemical reactions under ambient conditions, harnessing solar energy and reducing the need for fossil fuels. Electrocatalysis: This uses electrical energy to drive chemical reactions, often in the production of fuels such as hydrogen. It can be paired with renewable energy sources to create a sustainable cycle.
