Transparent free-standing film of 1-D rutile/anatase TiO2 nanorod arrays by a one-step hydrothermal process.

ABSTRACT

Through the addition of a solid-state precursor, a large-scale, transparent, and free-standing film of 1-D rutile/anatase TiO2 nanorod arrays can be fabricated by dynamically changing the acidity and concentrations of titanium and chloride ions, and creating anatase growth-friendly conditions.
