Abstract

The escalating presence of organic pollutants from industrial activities necessitates urgent measures for their degradation, given their adverse effects on environmental health and ecosystem equilibrium. This study explores the synthesis and characterization of bismuth oxychloride (BiOCl) and zinc oxide (ZnO)-doped BiOCl nanoparticles for enhanced photocatalytic applications. BiOCl, a versatile material with applications in various sectors including cosmetics, pharmaceuticals, and photocatalysis, was synthesized using a novel chemical approach devoid of thermal treatments. ZnO doping induced notable changes in the optical properties of BiOCl, leading to enhanced light absorption within the visible spectrum. Characterization techniques such as X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and UV-visible spectroscopy were employed to analyze the structural and optical properties of the synthesized materials. XRD analysis confirmed the crystalline nature of BiOCl and doped ZnO, while SEM revealed the morphology and microstructure of the nanoparticles. EDX analysis confirmed the elemental composition of the samples, indicating the presence of Bi, O, Cl, and Zn. UV-visible spectroscopy revealed a red shift in the absorption edge upon ZnO doping, with Tauc curves indicating a direct bandgap of 3.26 eV for BiOCl and 3.35 eV for ZnO-doped BiOCl. This research highlights the potential of ZnO-doped BiOCl nanoparticles as efficient photocatalysts for environmental remediation applications.

用于可见光驱动光催化的 ZnO 掺杂 BiOCl 纳米粒子

鉴于工业活动中有机污染物对环境健康和生态系统平衡的不利影响，有必要采取紧急措施降解这些污染物。本研究探讨了氧氯化铋（BiOCl）和氧化锌（ZnO）掺杂的 BiOCl 纳米粒子的合成和表征，以增强其光催化应用。BiOCl 是一种多用途材料，可应用于化妆品、医药和光催化等多个领域。氧化锌的掺杂使 BiOCl 的光学特性发生了显著变化，从而增强了对可见光谱内光的吸收。研究人员采用了 X 射线衍射（XRD）、拉曼光谱、扫描电子显微镜（SEM）、能量色散 X 射线光谱（EDS）和紫外可见光谱等表征技术来分析合成材料的结构和光学特性。XRD 分析证实了 BiOCl 和掺杂 ZnO 的结晶性质，而 SEM 则揭示了纳米颗粒的形态和微观结构。EDX 分析证实了样品的元素组成，表明其中含有 Bi、O、Cl 和 Zn。紫外可见光谱显示，掺杂 ZnO 后，吸收边发生了红移，陶氏曲线表明 BiOCl 的直接带隙为 3.26 eV，而掺杂 ZnO 的 BiOCl 为 3.35 eV。这项研究凸显了氧化锌掺杂的 BiOCl 纳米粒子作为高效光催化剂在环境修复应用中的潜力。
