| 中文摘要 | 環丙沙星 (CIP) 是最典型的氟喹諾酮類抗生素，並且越來越多地在水環境中檢測到。為了消除水中的 CIP，透過蝕刻工程技術開發了一種中空工程奈米結構鈷嵌入氮摻雜碳 (H-Co@NC)。H-Co@NC 呈現立方形形態，中空結構被海膽狀薄層覆蓋，而鈷 (Co) 奈米粒子嵌入整個表面。因此，H-Co@NC 對 Oxone 活化以消除水中的 CIP 表現出顯著的催化活性，並且優於非空心類似物 S-Co@NC 和商業 Co3O4。測得的活化能 (Ea) 為 48.2 kJ mol−1，低於大多數 CIP 降解催化劑的報告值。基於理論計算和檢測到的中間體，也提出了H-Co@NC + Oxone對CIP的降解途徑。H-Co@NC + Oxone 同時產生 SO4˙−、OH˙ 和 1O2，其中 SO4˙− 在 CIP 降解中發揮主導作用。此外，H-Co@NC 在多循環 CIP 降解過程中仍能保持其結構，並在各種水基質中保持高效。根據生態毒性評估，H-Co@NC + Oxone 的 CIP 降解在其分解過程中不會導致有毒和劇毒副產物的形成。這些特徵驗證了 H-Co@NC 是一種有利且有前途的多相催化劑，用於活化 Oxone 以消除水系統中的 CIP。 |
| 英文摘要 | Ciprofloxacin (CIP) represents the most typical fluoroquinolone antibiotic and is increasingly detected in water environments. For eliminating CIP from water, a hollow-engineered nanostructured cobalt-embedded nitrogen-doped carbon (H-Co@NC) is developed through an etching-engineering technique. H-Co@NC exhibits a cubiform morphology with a hollow configuration covered by thin urchin-like layers, whereas cobalt (Co) nanoparticles are embedded throughout the entire surface. Thus, H-Co@NC shows remarkable catalytic activities for Oxone activation to eliminate CIP from water and outperforms the non-hollow analogue, S-Co@NC, and the commercial Co3O4. The activation energy (Ea) was measured as 48.2 kJ mol−1, which is lower than that reported for most of the catalysts for CIP degradation. The degradation pathway of CIP by H-Co@NC + Oxone is also proposed based on theoretical calculations and detected intermediates. SO4˙−, OH˙, and 1O2 are simultaneously generated from H-Co@NC + Oxone, in which SO4˙− shows a dominant role in the CIP degradation. Besides, H-Co@NC preserves its structure over multi-cycle CIP degradation and remains highly effective in various water matrices. CIP degradation by H-Co@NC + Oxone does not lead to the formation of toxic and very toxic by-products during its decomposition process by the eco-toxicity assessment. These features validate that H-Co@NC is an advantageous and promising heterogeneous catalyst for activating Oxone to eliminate CIP from aqueous systems. |
