water splitting
/ˈwɔːtər ˈsplɪtɪŋ/ · wa·ter split·ting
noun
- The process of separating water (H₂O) into its constituent gases, hydrogen and oxygen, typically by electrolysis or photolysis. Researchers are seeking cheaper catalysts to make large‑scale water splitting economically viable.
- A field of study concerned with developing methods and materials that efficiently perform water splitting for energy applications. Her PhD focuses on nanostructured photocatalysts for solar‑driven water splitting.
