摘要：
In this study, we grew TiO2 nanorods on TiO2-film buffered FTO substrate using modified chemical bathdeposition (M-CBD). The TiO2 buffer layer was grown by spin coating method with different RPM (revolutions per minute) values and deposition cycles. We investigated the effects of the RPM values and the deposition cycles on the morphological, structural and photoelectrochemical properties of TiO2 nanorods. In this work, we have also found that the morphological and structural properties of TiO2 nanorods affected the photoelectrochemical properties of TiO2 nanorods. And the maximum photocurrent density of 0.34 mA/cm(2) at 0.6V (vs.SCE) was obtained from the buffer layer deposition process condition of 4,000 RPM and two-times buffer layer depositions.
