Water splitting

$this->bbcode_second_pass_quote('', 'A') team of Italian scientists has created a sunlight-powered cell that produces pure hydrogen from water.

The new cell has two compartments filled with water and separated by an electrode made of platinum and titanium dioxide. When it is illuminated, by sunlight or an ordinary lamp, the electrode catalyses the splitting of the water into hydrogen and oxygen gas.
