The water splitting process takes place in an electrochemical cell containing water and a metallic electrode. When a voltage is applied to the electrode, the water splits into oxygen and hydrogen via ...

The study is published in the journal Nature Communications. "When you split water, two half-reactions occur," said Northwestern's Franz Geiger, who led the study. "One half-reaction produces hydrogen ...

Water splitting has long been hailed as a promising path to clean hydrogen fuel. But while the process looks elegant on paper, it turns out to be far less efficient in practice, demanding ...

Scandium-doped titanium dioxide (TiO 2) significantly enhances photocatalytic water splitting efficiency, achieving an apparent quantum yield of 30.3% and a solar-to-hydrogen efficiency of 0.34%.
