What was discovered
A titanium dioxide electrode illuminated with ultraviolet light splits water into hydrogen and oxygen. It founded photocatalysis, used in self-cleaning surfaces and in research on solar hydrogen.
Published in Nature in 1972.
What it led to
- self-cleaning and anti-fog surfaces
- solar hydrogen production
- dye-sensitised solar cells
