has high thermal stability of phase transformation

and Anatase was transformed to rutile after calcined at 1 100 ℃

which is 300 ℃ higher than that reported previously.The surface areas of samples calcined at 300 ℃ and 500 ℃ are 138 m

respectively.The obtained sample possesses high crystallinity and high surface area

which would be promising in the photocatalysis and photoelectrical chemical conversion etc.
