We reported a direct and tunable strategy to obtain a highly porous nanostructured Cu/Cu₂O/CuO@C by self-sacrificial HKUST-1 template pyrolysis. The as-synthesized composite was structurally characterized by X-ray photoelectron spectroscopy (XPS), X–ray powder diffraction (XRD), scanning electron microscope (SEM), and Fourier-transform infrared spectroscopy (FT-IR). The characteristic results demonstrated the existence of various species of copper oxides supported on carbon matrix. The surface of Cu/Cu₂O/CuO@C monitored many functional groups/chemical bonds, hollow structure as well as high surface area (∼80 m²/g). In addition, the effect of contact time, initial concentration, solution pH and ionic strength on the adsorption of ciprofloxacin (CIP) and tetracycline (TTC) on Cu/Cu₂O/CuO@C have been vigorously indicated. The results also revealed the adsorption of CIP and TTC obeyed pseudo-second order model and this process was endothermic and spontaneous. We also proposed several plausible adsorption mechanisms based on hydrogen bonding, π–π, and n–π interactions. The adsorbability efficiencies (Q_m, mg/g) of Cu/Cu₂O/CuO@C towards CIP and TTC from water were found, at 67.5 and 112.5 mg/g, respectively, along with excellent recyclability in comparison with other adsorbents.

我们报告了直接和可调策略，通过自我牺牲HKUST-1模板热解获得高度多孔的纳米结构Cu / Cu ₂ O / CuO @ C。合成后的复合材料在结构上通过X射线光电子能谱（XPS），X射线粉末衍射（XRD），扫描电子显微镜（SEM）和傅里叶变换红外光谱（FT-IR）进行了表征。特征结果证明了负载在碳基质上的各种铜氧化物的存在。Cu / Cu ₂ O / CuO @ C的表面监测了许多官能团/化学键，中空结构以及高表面积（〜80 m ²/G）。另外，已经强烈指出了接触时间，初始浓度，溶液pH和离子强度对环丙沙星（CIP）和四环素（TTC）在Cu / Cu ₂ O / CuO @ C上的吸附作用。结果还表明CIP和TTC的吸附遵循伪二级模型，并且该过程是吸热的和自发的。我们还基于氢键，π–π和n–π相互作用提出了几种可能的吸附机理。发现Cu / Cu ₂ O / CuO @ C从水中对CIP和TTC的吸附效率（Q _m，mg / g）分别为67.5和112.5 mg / g，与其他吸附剂相比具有出色的可回收性。
