As the global pursuit for sustainable energy solutions intensifies, water splitting remains a promising avenue for producing clean hydrogen fuels. But the process of splitting water into hydrogen and oxygen is inherently inefficient—requiring significantly more energy than theoretically predicted.
Now, Northwestern University chemists have found a molecular-level explanation for this discrepancy. In the crucial moment before giving up oxygen atoms, the water molecules perform an unexpected trick: They flip.
After observing the water molecules flip, the team quantified the precise energy cost associated with that critical step. They discovered the acrobatic act is a major…
