摘要

在此,我们利用玻璃毛细管开发了一种光催化反应器,由于在玻璃毛细管内表面生长了氧化锌(ZnO)纳米结构,该反应器既是流动池,又是薄膜支撑的光催化剂。通过 X 射线衍射 (XRD)、场发射扫描电子显微镜 (FESEM)、能量色散 X 射线光谱 (EDAX)、紫外可见光谱和拉曼光谱等表征方法研究了氧化锌纳米结构的结构、形态、元素和光学特性。此外,还利用染料敏化氧化锌纳米结构在可见光照射下进行光催化应用。利用 ZnO 改性玻璃毛细管开发了一种定制装置,用于同时衰减和测量可见 LED 光下的染料降解过程。该模型可用于设计便携式光催化反应器,通过实时测量准确监控染料降解过程。

ZnO-modified glass capillaries as a portable photocatalytic reactor for real-time measurements
Here, we have developed a photocatalytic reactor using glass capillaries which acts both as a flow cell and a thin film-supported photocatalyst due to the Zinc Oxide (ZnO) nanostructures grown on the inner surface of the glass capillaries. The structural, morphological, elemental, and optical characteristics of the ZnO nanostructures were investigated through characterization methods such as x-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive x-ray spectroscopy (EDAX), UV–Visible spectroscopy, and Raman spectroscopy. Further, dye-sensitized ZnO nanostructures were used for photocatalytic application under visible light irradiation. A custom-made setup is developed using ZnO-modified glass capillaries for simultaneous decay and measurement of the dye degradation process under visible LED light. This developed model could have future technological applications in designing portable photocatalytic reactors that can accurately monitor the dye degradation process using real-time measurements.
