Abstract

Doped materials have received substantial attention due to their increased usefulness in photocatalytic applications. Within this context, the present study was dedicated to investigating the potential of the precipitation technique for producing La-doped tungsten oxide (WO3). To comprehensively characterize the synthesized La-doped WO3, scanning electron microscopy and X-ray diffraction were judiciously employed. The focal point of the investigation encompassed an examination of the impact of varying La concentrations on multiple fronts: the photocatalytic activities (PCAs), as well as any associated structural and morphological modifications. This holistic approach aimed to uncover the intricate relationship between La incorporation and the resulting properties of the WO3 matrix. Through the degradation of Malachite green dye within an aqueous medium, PCA of the La-doped WO3 samples was quantitatively evaluated. Remarkably, over 180 min under irradiation of visible light irradiation, the achieved levels of dye degradation were remarkable, amounting to 81.165, 83.11, and 83.85% for the respective samples. These findings firmly underscore the potential of La-doped WO3 as a proficient photocatalyst, particularly in color removal from wastewater. This study paves the way for enhanced wastewater treatment approaches by utilizing doped WO3 materials.

改善 WO3 纳米粒子在可见光照射下降解孔雀石绿染料的光催化性能：掺杂 La 的影响

由于掺杂材料在光催化应用中的作用越来越大，因此受到了广泛关注。在此背景下，本研究致力于调查沉淀技术生产掺杂 La 的氧化钨（WO3）的潜力。为了全面描述合成的掺杂 La 的 WO3 的特性，研究人员采用了扫描电子显微镜和 X 射线衍射技术。调查的重点包括研究不同浓度的 La 对多个方面的影响：光催化活性 (PCA)，以及任何相关的结构和形态改变。这种综合方法旨在揭示掺入 La 与 WO3 基体所产生的特性之间错综复杂的关系。通过孔雀石绿染料在水介质中的降解，对掺入 La 的 WO3 样品的 PCA 进行了定量评估。值得注意的是，在可见光照射下，180 分钟内染料降解水平显著提高，各样品分别达到 81.165%、83.11% 和 83.85%。这些发现有力地证明了掺 La 的 WO3 作为高效光催化剂的潜力，尤其是在去除废水中的色素方面。这项研究为利用掺杂 WO3 材料改进废水处理方法铺平了道路。

期刊介绍： Open Chemistry is a peer-reviewed, open access journal that publishes original research, reviews and short communications in the fields of chemistry in an ongoing way. The central goal is to provide a hub for researchers working across all subjects to present their discoveries, and to be a forum for the discussion of the important issues in the field. The journal is the premier source for cutting edge research in fundamental chemistry and it provides high quality peer review services for its authors across the world. Moreover, it allows for libraries everywhere to avoid subscribing to multiple local publications, and to receive instead all the necessary chemistry research from a single source available to the entire scientific community.
