摘要

采用水下脉冲等离子体制备了Fe2O3修饰的Ni-Cr层状双氢氧化物复合材料，采用x射线衍射（XRD）、x射线光电子能谱（XPS）、扫描电子显微镜（SEM）、热重分析（TG）和振动样品磁强计（VSM）对复合材料进行了表征。在这个过程中，电极材料（Fe和NiCr导线）作为最终复合材料的前驱体。XRD、XPS和能谱分析（EDS）数据表明，在水下等离子体条件下形成了含氧化铁杂质的Ni-Cr层状双氢氧化物。热研究表明，所得复合材料表现出热稳定性。复合材料中氧化铁的含量影响其磁性能。对四环素的动力学吸附和释放实验表明，复合材料可作为高效的环境吸附剂。磁性颗粒（Fe2O3）的存在使吸附剂易于去除。

Plasma chemical synthesis of magnetic Fe2O3-Ni-Cr layered double hydroxide composites for environmental applications

The composites based on Ni-Cr layered double hydroxides decorated with Fe₂O₃ obtained through underwater pulsed plasma without the use of chemical precursors, were evaluated using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analysis (TG), and vibrating sample magnetometry (VSM). In this process, the electrode materials (Fe and NiCr wires) serve as precursors for the resulting composite. XRD, XPS, and energy-dispersive spectroscopy (EDS) data indicated that Ni-Cr layered double hydroxides with iron oxide impurities are formed under underwater plasma conditions. Thermal studies demonstrated that the resulting composites exhibit thermal stability. The content of iron oxides within the composite influences their magnetic properties. The kinetic sorption of tetracycline from aqueous solution as well as its release showed that the obtained composites can be used as efficient adsorbents for the environmental applications. The presence of magnetic particles (Fe₂O₃) facilitates the easy removal of the sorbent.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
