Artificial photosynthesis—creating renewable fuels from sunlight, water, and carbon dioxide in the laboratory—has the potential to transform the way our energy needs are met today. It also raises some of the most fundamental questions in chemistry and materials science. What are the intermediate states of photo-driven chemical reactions? How do we apply advanced spectroscopic tools to pinpoint the steps in a mechanistic pathway for fuel generation? Visit the research section to see how we tackle these questions.
