How can femtochemistry help fight climate change?
Femtochemistry can help fight climate change by revealing the fundamental steps in energy conversion processes. For instance, photosynthesis is nature's way of capturing sunlight and storing it as chemical energy—a process that involves ultrafast electron transfer within femtoseconds. By understanding these dynamics, we can design artificial photosynthetic systems that split water into hydrogen and oxygen more efficiently, producing clean fuel. My work on the ultrafast dynamics of the chemical bond provides a blueprint for this: we can watch how energy flows through molecules and identify bottlenecks that waste energy. Similarly, studying catalytic reactions at femtosecond timescales can improve the efficiency of carbon dioxide reduction, turning a greenhouse gas into useful fuels. Science knows no borders, and this is a global challenge. The future belongs to those who believe in the beauty of their dreams—and using light to create a sustainable energy cycle is one of the most beautiful dreams we can pursue.
