摘要: 以钛片为基底材料，采用阳极氧化法刻蚀纳米二氧化钛(TiO2)管阵列，并进行二次阳极氧化获得排列规整的管阵列。以葡萄糖为碳源通过高压水热反应掺碳获得TiO2-C/Ti，采用电镀法在其表面电沉积NiSn合金制得NiSn/TiO2-C/Ti电极。用透射电镜(TEM)、X射线衍射(XRD)等进行表征，探究不同的反应条件对NiSn/TiO2-C/Ti电极催化性能的影响。实验结果表明，电极表面的TiO2呈管状结构且排列规整，由金红石和锐钛矿混晶组成。当外加电压为5 V，甲基橙溶液的pH为3时，电极的光电催化性能最佳，在90 min内对10 mg/L甲基橙溶液的降解率达到97.4%。
Abstract: Titanium dioxide (TiO2) nanotube arrays were etched by anodic oxidation method using titanium sheet as the substrate material, and then anodized twice to obtain regular tube arrays. NiSn/TiO2-C/Ti electrode was prepared by electrodeposition of NiSn alloy on the surface of TiO2-C/Ti, which was obtained by high pressure hydrothermal reaction with glucose as carbon source. The samples were characterized by transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) and the influence of different reaction conditions on the solar photoelectrocatalytic performance was investigated. The experiment results showed that the TiO2 on the electrode surface is tubular structure and regular arrangement, which is composed of rutile and anatase mixed crystal. The optimum conditions were applied voltage 5 V, pH of methyl orange solution 3, and the degradation rate of 10 mg/L methyl orange solution reached 97.4% in 90 min.
