摘　　要：本文采用乙醇作为添加剂,通过低温水热法在透明导电玻璃衬底上制备晶化良好的金红石相TiO_(2)纳米棒阵列。对样品进行了X射线衍射(XRD)、扫描电子显微镜(SEM)等结构形貌表征和光电化学性能测试。实验发现乙醇加入有利于前驱物水解缩聚反应,同时提高水热反应压力,促进TiO_(2)晶粒低温成核和生长,从而实现70℃直接在基底表面生长出TiO_(2)纳米棒阵列。通过调控水热反应温度、时间以及乙醇添加量等参数可有效调控TiO_(2)纳米棒阵列的形貌,改善其光电化学性能。同时低温水热制备工艺也降低了对衬底材料的限制,拓展了TiO_(2)纳米棒阵列的应用领域,表现出良好的应用前景。Using ethanol as an additive,we prepared well-crystalline rutile phase TiO_(2)nanoroodarrays on a transparent conductive glass substrate by low-temperature hydrothermal method.The structures were characterized by X-ray diffraction(XRD),scanning election microscopy(SEM),characterization of the structural morphology and the photochemical properties were alsotested.The experiment found that the addition of ethanol favored the hydrolysis and condensationreaction of the precursor,increased the hydrothermal reaction pressure,and promoted the lowtemperature nucleation and growth of TiO_(2)grains,thus realizing the direct growth of 70℃of the TiO_(2)nanorood array on the base surface.By regulating the temperature and time of ethanoladdition,the morphology of the TiO_(2)nanorod array can be effectively regulated and thephotochemical properties are improved.At the same time,the low temperature hydrothermalpreparation process also reduces the limitation on substrate materials,expands the applicationfield of TiO_(2)nanorod array,and shows good application prospects.
