Hydrogen photoelectrolysis

Numerous approaches involving a variety of semiconductors have been explored for hydrogen photoelectrolysis since the early 1980s, but none... 

Fujishima and Honda [16, 158] reported the photodecomposition of water using semiconductor photoelectrolysis cells (Figure 4.10). When the surface of the Ti02 electrode was irradiated with UV light, oxygen evolution was observed at the Ti02 electrode surface and hydrogen at the Pt black electrode. The overall water photodecomposition reaction ...
