How to obtain mix phase TiO2 nanorod (anatase and rutile) on ITO glass by hydrothermal synthesis?

From my understanding, mix phase TiO2 (anatase and rutile) exhibit better conductive properties than pure phase TiO2.

My research is about growth of TiO2 nanorod perpendicular on ITO glass to fabricate DSSC. I choose Hydrothermal synthesis as synthesis route and from my result, I get rutile TiO2 nanorod only.

Can anyone explain about the anatase phase in my experiment?
