ABSTRACT:
The present invention provides a method for producing a titanium oxide. The method can be applied to produce a titanium oxide having a large specific surface area. The method typically entails calcinating at least one titanium oxide precursor selected from a titanium hydroxide and titanium peroxide, wherein the calcination occurs in the presence of nitrogen and at a steam pressure of at most about 8,000 Pa.
