Abstract:
A method for producing a catalyst component-carrying titania fiber which comprises:(i) adding water to a solution of a titanium alkoxide to carry out a hydrolysis reaction and a polymerization reaction of the titanium alkoxide to obtain a polymer in the reaction mixture;(ii) dissolving the polymer in the presence of an organic solvent in which the polymer dissolves to obtain a spinning solution;(iii) adding a catalyst component to at least one member selected from the groups consisting of a solution of a titanium alkoxide, the reaction mixture in (i) and the spinning solution in (ii);(iv) spinning the spinning solution to obtain a precursor fiber;(v) treating the precursor fiber with water vapor before and/or during calcination; and(vi) calcining the precursor fiber to obtain a catalyst component-carrying titania fiber.
