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, BiFeO/Cu(BDC) nanocomposite 1, and BiFeO/Cu(BDC) nanocomposite 2 have been studied by cyclic voltammetry.
在本研究中,分别通过微波辅助固态燃烧法和超声辅助法制备了铁酸铋纳米颗粒和金属有机框架Cu(BDC)。为了增强铁酸铋纳米颗粒和Cu(BDC)的性能,我们通过微波和超声探头策略将它们制成复合材料。采用了包括傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)、扫描电子显微镜(SEM)、漫反射光谱(DRS)、振动样品磁强计(VSM)等在内的各种分析方法来验证合成的准确性。然后,通过甲基橙的光催化降解来评估纳米颗粒和所制备的纳米复合材料的催化性能。此外,还评估了合成材料对废水中刚果红的吸附能力。所有结果证明,所提出的纳米复合材料可以成为去除废水中污染物的可接受候选材料。通过循环伏安法研究了铁酸铋、BiFeO/Cu(BDC)纳米复合材料1和BiFeO/Cu(BDC)纳米复合材料2的电化学性质。
