Abstract
The invention relates to a novel form of titanium oxide. The titanium oxide is characterized in that it has the crystallographic structure of rutile with an orthorhombic lattice and a Pnmm space group, it has a platelet morphology, the platelets being of rectangular shape with a length between 3 and 10 nm, a width between 3 and 10 nm and a thickness of less than 1 nm and it has a specific surface area, determined by nitrogen adsorption/desorption, of 100 to 200 m2/g. Applications: self-cleaning glazing, photovoltaic cells.
