Abstract

In this study, MOF/BiFeO₃ composite (MOF, metal-organic framework) has been synthesized successfully through a one-pot hydrothermal method. The MOF/BiFeO₃ composite samples, pure MOF samples and BiFeO₃ samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and by UV-vis spectrophotometry. The results and analysis reveal that MOF/BiFeO₃ composite has better photocatalytic behavior for methylene blue (MB) compared to pure MOF and pure BiFeO₃. The enhancement of photocatalytic performance should be due to the introduction of MOF change the surface morphology of BiFeO which will increase the contact area with MB. This composing strategy of MOF/BiFeO₃ composite may bring new insight into the designing of highly efficient photocatalysts.

摘要

在本研究中，通过一锅水热法成功合成了金属有机框架/铋铁氧体（MOF/BiFeO₃）复合材料（MOF，金属有机框架）。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、能谱仪（EDS）和紫外可见分光光度法对MOF/BiFeO₃复合材料样品、纯MOF样品和BiFeO₃样品进行了表征。结果与分析表明，与纯MOF和纯BiFeO₃相比，MOF/BiFeO₃复合材料对亚甲基蓝（MB）具有更好的光催化性能。光催化性能的提高应归因于MOF的引入改变了BiFeO的表面形貌，这将增加与MB的接触面积。MOF/BiFeO₃复合材料的这种复合策略可能为高效光催化剂的设计带来新的见解。
