Scientists spot water molecules flipping before they split
February 26, 2025
For the first time, scientists have observed water molecules splitting in real time to form hydrogen and oxygen. Just before splitting, Franz Geiger and first author Raiden Speelman saw the molecules unexpectedly flip 180 degrees, revealing a crucial explanation for the higher energy required. This insight could lead to more efficient water splitting, offering potential for cheaper clean hydrogen fuel and breathable oxygen for future Mars missions.
