摘要:

采用二次阳极氧化法在NH₄F-(NH₄)₂SO₄复合电解液中制备近似莲藕状TiO₂纳米管阵列(TNTAs)。通过XRD、SEM、PL(光致发光光谱)等手段研究了不同阳极氧化电压下制备的TNTAs的结构、形貌以及光生载流子的分离率。同时，在模拟太阳光下，通过测试光生电流密度评估其光电化学性能，通过测试开路电位、Tafel极化电位和EIS拟合曲线评估对304SS的阴极保护效果。结果显示，当阳极氧化电压为25 V时，TNTAs莲藕状清晰，规整度较高，光生载流子分离率高，光生电流密度达到最高值为309.2 µA·cm^-2，开路电位达到最低值-0.986 V( vs. Ag/AgCl)时，对304SS的阴极保护效果较好。

Abstract：

At present, TiO₂, as a low-cost and non-polluting N-type semiconductor material, has been applied to photogenerated cathodic protection technology due to its excellent photoelectric conversion performance. In comparison with the ordinary nanotube arrays, the highly ordered lotus root-like TiO₂ nanotube arrays (TNTAs) present much larger specific surface area and more effective photoreaction sites, which is conductive to enhancing the photoelectrochemical properties of TiO₂ nanotube arrays. In this paper, lotus root-like TiO₂ nanotube arrays were prepared by a two-step anodization process in NH₄F-(NH₄)₂SO₄composite electrolyte. The effect of different anodization voltages on the performance of TiO₂ nanotube photoanodes was studied. The structure, morphology and separation rate of photogenerated carriers of TNTAs prepared by different appllied anodic oxidation voltages were studied by XRD, SEM and photoluminescence spectra (PL). At the same time, under the irradiation of a simulated sunlight, the photoelectrochemical performance was evaluated by the photocurrent density measurement, and the cathodic protection effect of the photoanode on 304 stainless steel was evaluated by measurements of open circuit potential and Tafel polarization potential, as well as by fitting EIS curves. The results show that when the anodic oxidation voltage is 25 V, TNTAs have clear lotus root-like shape, high regularity, high photogenerated carrier separation rate and high photogenerated current density. Accordingly, the prepared TNTAs present lower open circuit potential, while better cathodic protection effect for 304 stainless steel substrates.
