摘      要：Well-aligned TiO2 nanorod arrays （TNAs） were prepared on pretreated quartz substrates via hydrothermal *** effect of the different preparation conditions on the growth morphologies of TNAs was systematically investigated by X-ray diffraction （XRD） and field-emission scanning electron microscopy （FE-SEM）.The photocatalytic properties were tested by photodegradation of a methyl blue *** is demonstrated that the hydrothermal reaction conditions,such as precursor concentration,hydrothermal reaction temperature,and hydrothermal reaction times,can greatly affect the growth of *** the preparation process,TNAs with 2 μm in length and 140-170 nm in diameter and well-aligned orientation have been successfully *** photocatalytic experiment results indicate that TNAs have much better photocatalytic activity than TiO2 nanoparticles.
