水热合成工艺对TiO2纳米棒阵列形貌和结构的影响

摘要

TiO2 nanorod arrays had been successfully prepared by hydrothermal methods. The effects of hydrothermal time on structure properties of TiO2 nanorod arrays were studied. The characterization of TiO2 nanorod arrays were measured by XRD and SEM. The results show the growth of TiO2 nanorod arrays depend on reaction time. The crystal structure of the light anode is rutile type. The best water thermal parameters: the ratio of hydrochloric acid and deionized water is 1.0, the content of titanium butyl acrylate acid is 2.5%, the reaction temperature is 150℃ and reaction time is 20h. And the mechanism of hydrothermal synthesis of TiO2 nanostructures is further explored.%通过水热合成方法制备TiO2纳米棒阵列，并且研究水热合成时间对TiO2纳米棒阵列形貌及其结构的影响。利用SEM和XRD对样品进行了分析和表征，结构表明：水热合成时间对形貌和结构影响比较大，光阳极的晶型结构均为金红石型，确定了最佳的水热反应参数：去离子水与盐酸比例为1.0、钛酸丁酯含量为2.5%、反应温度为150℃、反应时间为20 h，并进一步探讨了水热合成TiO2纳米结构的机理。
