通过水热法在钛基板上成功制备出了不同形貌的 Bi25 FeO 40纳米材料,使用 XRD 和 FE-SEM 对水热反应过程中反应的温度(160~200℃)、矿化剂的种类和浓度对产物结构及形貌的影响进行了研究,并对其生长机理进行分析。测试 Bi25 FeO 40的 UV-Vis漫反射光谱,发现其在波长400~600 nm 范围内具有良好的可见光响应;采用三电极体系测试材料的光电化学性能,结果显示纳米棒状产物对光电流的响应最快。
Sillenite type Bi2 5 FeO 40 has been used as the research subjects in this paper.Various Morphologies of Bi2 5 FeO 40 nano-materials have been successfully synthesized by hydrothermal method on the titanium substrate. The effect of processing parameters such as reaction temperature(1 60-200 ℃),mineralizer and stoichiometry was investigated by XRD and FE-SEM.Bi2 5 FeO 40 are found to have a good visible response ability from 400 to 600 nm through UV-Vis diffuse reflectance spectroscopy.The photo-electrochemical properties were measured by three electrodes measurements.The sample of nanorods morphology responded rapidly when irradiation.
