In this work, nanoporous carbon (NPC) was synthesized by direct carbonization of MOF-5 (a famous metal–organic framework). The structure and morphology of the prepared MOF-derived nanoporous carbon (MOF-NPC) were investigated by X-ray diffraction, N2 adsorption/desorption isotherm, Raman spectroscopy, thermogravimetric analysis, and scanning electron microscopy methods. The MOF-NPC was then used to adsorb copper ions from aqueous solutions. To evaluate the performance of the prepared MOF-NPC to remove copper ions, both adsorption kinetics and adsorption equilibrium experiments were carried out and then the obtained data were modeled with various models. Also, the efficacy of temperature and the pH of the solution on the removal efficiency were checked. The results show that the prepared MOF-NPC is a superadsorbent for the removal of copper ions from aqueous solutions. Finally, the removal percentage of copper ions by the prepared MOF-NPC was compared with other activated carbon adsorbents to show its incredible efficiency.

MOF-5衍生的纳米多孔碳：铜离子的超级吸附剂
在这项工作中，纳米孔碳（NPC）是通过MOF-5（著名的金属有机框架）直接碳化而合成的。通过X射线衍射N 2研究了制备的MOF衍生的纳米多孔碳（MOF-NPC）的结构和形貌。吸附/解吸等温线，拉曼光谱，热重分析和扫描电子显微镜方法。然后将MOF-NPC用于从水溶液中吸附铜离子。为了评估制备的MOF-NPC去除铜离子的性能，进行了吸附动力学和吸附平衡实验，然后使用各种模型对获得的数据进行建模。另外，检查温度和溶液的pH对去除效率的功效。结果表明，制备的MOF-NPC是从水溶液中去除铜离子的超级吸附剂。最后，将制得的MOF-NPC对铜离子的去除率与其他活性炭吸附剂进行比较，以显示其令人难以置信的效率。
