In this study, bismuth ferrite nanoparticles and metal-organic framework, Cu(BDC), were prepared by microwave-assisted combustion in solid state and ultrasound-assisted method, respectively. To enhance the properties of bismuth ferrite nanoparticles and Cu(BDC), we form them as their composite through microwave and ultrasonic probe strategies. Various analyses, including FT-IR, XRD, SEM, DRS, VSM, and so on, were applied to verify the synthesis accuracy. Then, the catalytic performances of the nanoparticles and the as-prepared nanocomposites were evaluated through photocatalytic degradation of methyl orange. Furthermore, the adsorption capacity of the as-synthesized materials was assessed toward the Congo red removal from wastewater. All the results prove that the proposed nanocomposite can be an acceptable candidate for eliminating contaminants from wastewater. The electrochemical properties of bismuth ferrite, BiFeO3/Cu(BDC) nanocomposite 1, and BiFeO3/Cu(BDC) nanocomposite 2 have been studied by cyclic voltammetry.

用于高效染料去除的新型磁性纳米复合材料 BiFeO3/Cu（BDC）

本研究分别采用微波辅助固态燃烧法和超声辅助法制备了铁氧体铋纳米颗粒和金属有机框架 Cu（BDC）。为了增强铋铁氧体纳米颗粒和 Cu（BDC）的性能，我们通过微波和超声探针策略将它们形成它们的复合材料。应用各种分析，包括 FT-IR、XRD、SEM、DRS、VSM 等，以验证合成精度。然后，通过光催化降解甲基橙评价纳米颗粒和制备的纳米复合材料的催化性能。此外，还评估了合成材料的吸附能力，以从废水中去除刚果红。所有结果都证明，所提出的纳米复合材料可以成为消除废水中污染物的可接受候选者。通过循环伏安法研究了铁氧体铋、BiFeO3/Cu（BDC）纳米复合材料 1 和 BiFeO3/Cu（BDC）纳米复合材料 2 的电化学性能。
