Researchers at University College London (UCL) have broken through to understanding of the properties of titanium dioxide known as ‘titania’ that is hoped to be used in photoelectrochemical cells known as PECs.
The basis of the research clears up a decades old misunderstanding that’s clouded the knowledge of how mixed phase titania catalysts operate. Mixed phase titania catalysts work by combining two different crystalline structures of titania. While titania’s chemical formula is always the same – one titanium and two oxygen atoms – its molecules can be arranged in different ways, producing different crystal structures and properties.
