Abstract EN
The performance of bare TiO2 photoanodes in photoelectrochemical devices and other applications is suboptimal due to the narrow light absorption range and poor electron-hole separation.
Here, heterostructured films of Ni-doped lead titanate (PbTi1−xNixO3, PTN)-coated titania (TiO2) nanorod arrays were fabricated via a two-step process comprising hydrothermal and sol-gel methods.
In the PTN/TiO2 composite films, the PTN component served as a visible light-responsive photosensitizer and the TiO2 nanorod was the electron transport layer.
When applied as photoanodes, the PTN/TiO2 films achieved the maximum photoconversion efficiency of ~2.6% and a photocurrent intensity of about 4 times higher than that of the PbTiO3/TiO2 film.
These results demonstrate that the ferroelectric material-coated TiO2 heterostructured films have high potential for application in photoelectric and optical devices.
