摘要

由于其固有的结构优势,二氧化钛纳米管在光电化学领域得到了广泛应用。然而,在有机电解液中进行阳极氧化的 TiO2 纳米管通常会在纳米管内部形成富碳层,从而经常干扰电荷转移和光催化反应。在本研究中,我们研究了对 TiO2 纳米管进行不同处理以消除阳极 TiO2 纳米管中的富碳层的方法。首先,研究了不同厚度 TiO2 的光电化学特性,并选择了 3.65 µm 的 TiO2 纳米管进行进一步处理。随后,通过不同的处理方法优化了 TiO2 的形态特性,以便将其用作光阳极。总之,通过机械研磨和化学蚀刻工艺处理的最佳 TiO2 纳米管可作为一种高效光阳极,其光电流增强至 0.2 mA/cm2,在 350 纳米波长下的 IPCE 为 59%,电荷转移电阻降低至 983 Ω。

Facile treatment to eliminate carbon-rich layer in TiO2 nanotube photoanodes

TiO2 nanotubes have been numerously utilized in photoelectrochemical field due to its intrinsic and structural advantages. However, TiO2 nanotubes anodized in organic electrolyte endemically involve carbon-rich layers inside of nanotubes, frequently interrupting charge transfers and photocatalytic reactions. In this study, we investigated some different treatments of TiO2 nanotubes to eliminate carbon-rich layers from anodic TiO2 nanotubes. Firstly, photoelectrochemical properties of TiO2 with various thickness were addressed, and the TiO2 nanotubes with 3.65 µm were selected for the further treatments. Subsequently, the morphological properties of TiO2 were optimized to be utilized as a photoanode through the different treatment methods. In conclusion, the optimal TiO2 nanotubes treated by mechanical grinding and chemical etching process behaved as an efficient photoanode with enhanced photocurrent of 0.2 mA/cm2, IPCE of 59% at 350 nm and lowered charge transfer resistance of 983 Ω.

期刊介绍: The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
