water splitting

Decomposing water molecules

Water splitting is the chemical process of breaking water molecules into hydrogen and oxygen, typically through electrolysis or photocatalysis.

The term appears most often in discussions of clean energy production, since hydrogen extracted this way can serve as fuel: Solar-powered water splitting could revolutionize renewable energy storage.
