| 中文摘要 | 由於水楊酸（SAC）是一種廣泛使用的藥物，考慮到水楊酸的毒性，將其排放到環境中已對生態造成嚴重威脅。因此，已採用涉及 SO4•− 的化學氧化方法來消除 SAC。由於單過硫酸鹽 (MPS) 已成為生產 SO4•− 的常用試劑，因此提出了一種替代的非均相 Co 基催化劑，該催化劑使用配位共價有機聚合物 (Co-COP) 作為前體。通過碳化，Co-COP 通過將 Co 離子轉化為 Co/CoO 納米顆粒和將 COP 轉化為 N 摻雜的碳納米膠囊 (CNC) 來轉移，以形成嵌入碳納米膠囊 (CoCNC) 的獨特的 Co NP 複合材料。由於 Co NPs 和 N 摻雜的 CNC 之間的協同作用，CoCNC 表現出比 Co3O4 納米顆粒更高的催化活性，用於激活 MPS 降解 SAC，N 摻雜 CNC 不僅充當載體，而且提供活性位點。因此，CoCNC+MPS 可以提供比報告值低得多的 SAC 降解 Ea 值（25.4 kJ/mol）。此外，即使在高濃度 NaCl 和 SDS 存在下，CoCNC 仍能有效去除 SAC。 CoCNC 還可以在多次循環中回收並保持其催化活性，這證實了 CoCNC 是 MPS 活化的有利催化劑。 |
| 英文摘要 | As salicylic acid (SAC) is an extensively used pharmaceutical, discharge of SAC into the environment has caused serious threats to ecology in view of its toxicity. Therefore, SO4•−-involved chemical oxidation methods have been employed for eliminating SAC. Since monopersulfate (MPS) has become a popular reagent for producing SO4•−, an alternative heterogeneous Co-based catalyst is proposed by using a Co-coordinated covalent organic polymers (Co-COP) as a precursor. Via carbonization, Co-COP is transferred by conversion of Co ions to Co/CoO nanoparticle and conversion of COP to N-doped carbon nanocapsules (CNC), respectively, to form a unique composite of Co NPs embedded into carbon nanocapsule (CoCNC). CoCNC exhibits a higher catalytic activity than Co3O4 nanoparticle for activating MPS to degrade SAC because of synergistic effects between Co NPs and the N-doped CNC which not only acts as the support but also provides active sites. Hence, CoCNC+MPS could afford a much lower Ea value (25.4 kJ/mol) of SAC degradation than the reported values. Moreover, CoCNC is still efficient for removing SAC even in the presence of high-concentration NaCl and SDS. CoCNC can be also recyclable over many cycles and maintain its catalytic activities, confirming that CoCNC is an advantageous catalyst for MPS activation. |
