Nanoporous carbon material loaded with zero-valent copper NPC@Cu was synthesized by one-step carbonization method using copper-based MOF (HKUST-1, [Cu₃(BTC)₂], BTC as 1,3,5-benzenetricarboxylic acid) as template. With NPC@Cu as catalyst, peroxymonosulfatesulfate (PMS) was activated as oxidant to treat simulated azo dye wastewater by heterogeneous catalytic oxidation at ambient pressure and room temperature. The catalysts were characterized by electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), etc. The effect of degradation efficiency of the catalyst dosage, oxidant dosage and initial pH during the reaction were studied. The experimental results showed that the degradation rate of 0.10 mmol/L RhB can reach 100% after 45 minutes of reaction at a catalyst dosage of 0.1 g/L, a PMS concentration of 2.00 mmol/L and a initial pH of 7. Through the free radical trapping experiment, it proved that there are two free radicals in the system—SO₄^–·and ·OH, and NPC@Cu is a catalytic material with good catalytic performance.

以铜基MOF (HKUST-1, [Cu₃(BTC)₂], BTC为1,3,5-苯三甲酸)为模板, 利用一步碳化法制备负载零价铜的纳米多孔碳材料NPC@Cu。以此 NPC@Cu为催化剂, 活化过一硫酸氢钾(PMS), 在常温常压下异相催化氧化处理模拟的偶氮染料废水。采用电子显微镜(SEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)等技术对催化剂进行表征, 并研究反应过程中催化剂投加量、氧化剂投加量和初始pH值对降解效率的影响。实验结果表明, 在催化剂用量为0.1 g/L, PMS浓度为2.00 mmol/L, pH值为7的条件下, 反应进行45分钟后, 浓度为0.10 mmol/L的RhB降解率可达到 100%。通过自由基捕捉实验, 证明体系中存在SO₄^–·和·OH两种自由基,表明NPC@Cu是一种性能良好的催化材料。
