摘要
我们采用一种不含氟化氢的创新机械化学方法，毫不费力地合成了可承受化学挑战的 Fe3O4/MIL-100（Cr）复合材料。作为开创性的一步，我们在 MIL-100（Cr）上原位添加了 Fe3O4，以探索其通过光-芬顿过程降解曙红（EY）的能力。我们使用 PXRD 和 FT-IR 进行的分析表明，在添加 Fe3O4 后，MIL-100(Cr) 的基本结构没有发生变化。然而，添加这种金属氧化物会导致 MIL-100(Cr) 的 BET 表面积、体积和孔径减小。有趣的是，我们的 FESEM-EDX 研究显示，Fe3O4 在 MIL-100(Cr) 基质中分布均匀。在我们合成的复合材料中，20% 的 Fe3O4/MIL-100(Cr)混合物表现出了显著的光-芬顿活性，在使用汞灯的最佳条件下，150 分钟内实现了令人印象深刻的 93.31% 的 EY 降解。在光-芬顿系统中，复合材料、过氧化氢和光之间的协同作用是增强去除 EY 的主要驱动力，在温和的反应条件下将其转化为无害的 CO2 和 H2O。
Efficient Photo-Fenton Degradation of Eosin Yellow with Solvent-Free Synthesized Fe3O4/MIL-100(Cr)
Fe3O4/MIL-100(Cr) composites, designed to withstand chemical challenges, were effortlessly synthesized using an innovative mechanochemical approach free from hydrogen fluoride. In a groundbreaking step, we adorned MIL-100(Cr) with Fe3O4in-situ to explore its ability to degrade Eosin Yellow (EY) through the photo-Fenton process. Our analyses using PXRD and FT-IR revealed no alterations in the fundamental structure of MIL-100(Cr) upon Fe3O4 modification. However, the addition of this metal oxide led to a reduction in MIL-100(Cr)’s BET surface area, volume, and pore diameter. Fascinatingly, our FESEM-EDX studies revealed a uniform distribution of Fe3O4 within the MIL-100(Cr) matrix. Among our synthesized composites, the 20% Fe3O4/MIL-100(Cr) blend exhibited remarkable photo-Fenton activity, achieving an impressive 93.31% EY degradation within 150 min under optimal conditions employing a Hg lamp. The synergy between the composite, hydrogen peroxide, and light in the photo-Fenton system emerged as the primary driving force behind the enhanced removal of EY, transforming it into harmless CO2 and H2O under mild reaction conditions.
