Abstract

The method produces a catalyst containing titanium oxide as a primary ingredient and is prepared from a titanium oxide-containing starting material through a titanium oxide precursor containing a suitable meta or ortho-titanic acid. Meta or ortho-titanic acid is obtained through a hydrothermal process step carried out in the presence of a suitable flocculent or colloid.
