摘要

本研究报道了通过直接水热合成和热分解制备Pd-TiO₂/ZnFe₂O₄纳米复合材料。利用x射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、x射线光电子能谱（XPS）、扫描电子显微镜（SEM）、能量色散x射线（EDX）、元素映射、uv -可见漫反射光谱（UV-DRS）和光致发光（PL）分析等技术对合成材料的结构、形态和光学特性进行了研究。与纯tio2相比，pd - tio2 /ZnFe₂O₄纳米复合材料在紫外和可见光区域均表现出增强的光吸收。通过辐照降解环丙沙星，考察了其光催化效率。该复合材料对TiO 2和TiO 2 /ZnFe₂O₄表现出优异的降解性能，在中性pH下达到最佳效果(7)。此外，该催化剂在连续5次重复使用循环中保持了其稳定性和活性。这些发现突出了Pd-TiO₂/ZnFe₂O₄作为一种高效的太阳能驱动光催化剂在废水处理中的应用潜力。

Pd-TiO2/ZnFe2O4 photocatalyst for photocatalytic degradation of ciprofloxacin under solar light irradiation

This study reports the preparation of a Pd-TiO₂/ZnFe₂O₄ nanocomposite via a straightforward hydrothermal synthesis followed by thermal decomposition. The structural, morphological, and optical characteristics of the synthesized material were examined using techniques such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), elemental mapping, UV–visible diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. The Pd-TiO₂/ZnFe₂O₄ nanocomposite exhibited enhanced light absorption across both UV and visible regions in comparison to pure TiO₂. Its photocatalytic efficiency was tested by degrading ciprofloxacin under irradiation. The composite demonstrated superior degradation performance over TiO₂ and TiO₂/ZnFe₂O₄, achieving the best results at neutral pH (7). Additionally, the catalyst retained its stability and activity over five consecutive reuse cycles. These findings highlight the potential of Pd-TiO₂/ZnFe₂O₄ as an efficient solar-driven photocatalyst for wastewater treatment applications.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
