- 摘要：Oriented TiO2 nanorod arrays were directly synthesized on fluorine-doped tin oxide glass substrates through a hydrothermal method. Experimental results demonstrate that a number of reaction parameters including acidity, reactant concentration, growth time and reaction temperature can affect the morphology and photocurrent density of TiO2 nanorods. For example, the length of the nanorods significantly increases with the growth time or reaction temperature, while the diameter is only influenced by reaction temperature but not growth time. Photocurrent density firstly improves but then decreases with the reaction temperature, and there are no clear correlations between photocurrent density and growth time. These results will provide helpful information on the optimization of reaction parameters for the synthesis of oriented rutile TiO2 nanorods with high photoelectrical conversion efficiency for solar cell applications.
