Abstract

Titanium oxysulfate (TiOSO

) was used as an inorganic titanium precursor to synthesize TiO

nanorods on a transparent

conductive fluorine-doped tin oxide (FTO) substrate by a facile hydrothermal process. The TiO

nanorod film was rutile phase and exhibited an array-cluster double-layered structure. Under the illumination of a solar simulator

the short-circuit photocurrent density of TiO

nanorods maximized at 0.17 mA/cm

which was over twice that of samples originating from organic titanium isopropoxide [Ti(

Pro)

] under the same conditions. Multi-dimensional structure and the participation of inorganic oxysulfate (OSO

) anion contribute to the enhanced photocurrent response of TiO

nanorod films.
