| 中文摘要 | 作為紫外光穩定劑，雙（4-羥基）二苯甲酮（BBP）被廣泛消耗以淬滅光氧化產生的自由基，鑑於其異激素毒性，BPs持續釋放到環境中對生態構成嚴重威脅，BBP應從水中去除以避免其不利影響。由於基於硫酸根 (SR) 的化學氧化技術已被證明是消除有機新興污染物的有效程序，本研究旨在通過激活 Oxone 開發有用的基於 SR 的程序以降解水中的 BBP。與傳統的 Co3O4 相比，硫化鈷 (CoS) 被特別提出作為一種替代的多相催化劑，用於激活 Oxone 以降解 BBP，因為 CoS 表現出更具反應性的氧化還原特性。由於催化劑的結構主要控制其催化活性，因此在本研究中，通過方便的一步工藝製備了獨特的納米板組裝 CoS（NPCS）3D 簇，作為一種有前途的多相催化劑，用於激活 Oxone 降解 BBP。 NPCS = 100 mg/L 和 Oxone = 200 mg/L，5 mg/L 的 BBP 可在 60 分鐘內完全消除。 NPCS 對 Oxone 活化的催化活性也顯著超過了參考材料 Co3O4，以增強 BBP 的降解。 NPCS 激活的 Oxone 降解 BBP 的 Ea 也被確定為 42.7 kJ/mol 的相對較低的值。通過實驗證據和密度泛函理論 (DFT) 計算研究和驗證了 NPCS 活化的 Oxone 降解 BBP 的活化機制和降解途徑，為使用 CoS 催化劑開發基於 SR 的 BBP 降解過程提供有價值的降解行為. |
| 英文摘要 | As UV-light stabilizers, Bis(4-hydroxy)benzophenone (BBP), are extensively consumed to quench radicals from photooxidation, continuous release of BPs into the environment poses serious threats to the ecology in view of their xenohormone toxicities, and BBP shall be eliminated from water to avoid its adverse effect. Since sulfate radical (SR)-based chemical oxidation techniques have been proven as effective procedures for eliminating organic emerging contaminants, this study aims to develop useful SR-based procedures through activating Oxone for degrading BBP in water. In contrast to the conventional Co3O4, cobalt sulfide (CoS) is particularly proposed as an alternative heterogeneous catalyst for activating Oxone to degrade BBP because CoS exhibits more reactive redox characteristics. As structures of catalysts predominantly control their catalytic activities, in this study, a unique nanoplate-assembled CoS (NPCS) 3D cluster is fabricated via a convenient one-step process to serve as a promising heterogeneous catalyst for activating Oxone to degrade BBP. With NPCS = 100 mg/L and Oxone = 200 mg/L, 5 mg/L of BBP can be completely eliminated in 60 min. The catalytic activity of NPCS towards Oxone activation also significantly surpasses the reference material, Co3O4, to enhance degradation of BBP. Ea of BBP degradation by NPCS-activated Oxone is also determined as a relatively low value of 42.7 kJ/mol. The activation mechanism as well as degradation pathway of BBP degradation by NPCS-activated Oxone was investigated and validated through experimental evidences and density functional theory (DFT) calculation to offer valuable insights into degradation behaviors for developing SR-based processes of BBP degradation using CoS catalysts. |
