Abstract

This study reports a successful synthesis of a novel Carbon@BaMoZrFe₁₂O₁₉ Mhexaferrite photocatalyst (NPs) using the coprecipitation method. Afterthat, the NPs were used as an activator for peroxymonosulfate (PMS) to remove ibuprofen (IBU) from water. NPs were subjected for a thorough characterization process utilizing various analytical techniques including XRD, FTIR, UV, PL TEM, SEM/EDS, and X-ray photoelectron spectroscopy (XPS). Significantly, the utilization of NPs for PMS activation demonstrated a notable improvement in the elimination of IBU under visible light. The research conducted a thorough investigation into the effects of various parameters, such as activating systems, initial pH, inorganic salts, IBU contents, and water matrix on the efficiency of IBU degradation. The significance of reactive oxygen species, such as sulfate and hydroxyl radicals, as well as singlet oxygen, in the removal of IBU, was clarified by chemical quenching tests. In addition, NPs exhibited competent magnetic separation and reprocessing capacities. The magnetic NPs revealed excellent constancy and recyclability, by sustaining degrading productivity after five consecutive cycles. Therefore, the present study offers a significant contributions to the understanding of photocatalytic degradation for organic pollutants through the utilization of magnetic photocatalysts.

用于去除布洛芬的新型碳@BaMoZrFe12O19 光催化过硫酸盐活化技术

本研究报告采用共沉淀法成功合成了一种新型碳@BaMoZrFe12O19六价铁氧体光催化剂（NPs）。随后，该 NPs 被用作过一硫酸盐 (PMS) 的活化剂，用于去除水中的布洛芬 (IBU)。利用各种分析技术，包括 XRD、FTIR、UV、PL TEM、SEM/EDS 和 X 射线光电子能谱 (XPS)，对 NPs 进行了全面的表征。值得注意的是，在可见光下，利用 NPs 活化 PMS 对消除 IBU 有明显改善。研究深入探讨了活化体系、初始 pH 值、无机盐、IBU 含量和水基质等各种参数对 IBU 降解效率的影响。通过化学淬灭试验，明确了活性氧（如硫酸根自由基、羟基自由基以及单线态氧）在去除 IBU 过程中的重要作用。此外，NPs 还表现出良好的磁分离和再处理能力。磁性 NPs 在连续五个周期后仍能保持降解生产力，显示出卓越的恒定性和可回收性。因此，本研究为了解利用磁性光催化剂光催化降解有机污染物做出了重要贡献。

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
