Metal-organic frameworks (MOFs) present as ideal platforms towards synthesizing metals/metal oxides self-supported in porous carbon matrix. Herein, we described an effective strategy to transform manganese-based MOFs, namely Mn₂(BDC)₂(DMF)₂, into [email protected] porous nanocomposite via a facile and one-pot pyrolysis procedure. Fourier-transform infrared spectroscopy (FT–IR) results indicated the transformation of coordination bonds into ionic bonds of Mn(II)–O. The morphological profiles also elucidated the MnO nanoparticles embedded carbonaceous structure while other physicochemical techniques such as X-ray photoelectron spectroscopy (XPS) demonstrated the important chemical bonds (e.g. CC in aromatic rings, CO in phenolic/alcoholic groups, CO in carbonyl groups, and OCO in carboxyl, etc.) on [email protected] surface. Uptake application of [email protected] for a wide range of antibiotic contaminants involving tetracycline (TCC), ciprofloxacin (CFX), diclofenac (DCF) and chloramphenicol (CAP) in aqueous phases was notably reported. Through the nonlinearization of kinetic and isotherm models, validation for maximum adsorption capacities could be attainable, at 79.9 mg/g (CAP) < 92.4 mg/g (DCF) < 170.3 mg/g (TCC) < 235.6 mg/g (CFX), indicating the great potential of [email protected] nanocomposite for removing many kinds of emergent antibiotics from the wastewater.

金属有机框架（MOF）作为合成多孔碳基质中自支撑的金属/金属氧化物的理想平台。在这里，我们描述了一种有效的策略，可通过便捷的一锅热解程序将锰基MOF（即Mn ₂（BDC）₂（DMF）₂）转变为[电子邮件保护的]多孔纳米复合材料。傅立叶变换红外光谱（FT-IR）结果表明，配位键已转变为Mn（II）-O的离子键。形态学特征还阐明了MnO纳米颗粒嵌入的碳质结构，而其他物理化学技术（如X射线光电子能谱（XPS））则表明了重要的化学键（例如芳环中的C C，[受电子邮件保护的]表面上的酚/醇基中的O，羰基中的C O和羧基中的O C O等）。据报道，[电子邮件保护]在水相中被广泛应用于涉及四环素（TCC），环丙沙星（CFX），双氯芬酸（DCF）和氯霉素（CAP）的多种抗生素污染物中。通过动力学和等温线模型的非线性化，可以达到最大吸附容量的验证，即79.9 mg / g（CAP）<92.4 mg / g（DCF）<170.3 mg / g（TCC）<235.6 mg / g（CFX） ，表明[电子邮件保护的]纳米复合材料具有从废水中去除多种新兴抗生素的巨大潜力。
