| 中文摘要 | 由於 2-羥基苯甲酸 (HBA) 是一種典型的藥物和個人護理產品 (PPCP)，HBA 不斷釋放到環境中會對生態造成威脅，因此開發有效的技術從水中去除 HBA 至關重要。最近，基於硫酸根（SO4radical dot-）的高級氧化工藝涉及單過硫酸鹽（MPS）活化被證明是從水中消除 PPCPs 的有效方法，並且 Co3O4 被認為是活化 MPS 的有效催化劑。因此，人們對開發具有有利形態和特性的 Co3O4 基催化劑以提高催化活性產生了極大的興趣。因此，在這項工作中提出了一種特殊的 Co3O4 基材料。通過表面活性劑輔助策略，製備了立方 Co-MOF 並將其用作前體，經過蝕刻得到中空結構，然後轉化為中空多孔 Co3O4 納米盒（PCNB）。與商業化的 Co3O4 NPs (com-Co3O4 NP) 相比，PCNB 可以表現出獨特的活性表面，具有豐富的表面氧空位以及物理性質，從而導致 PCNB 在活化 MPS 以降解 HBA 方面具有出色的催化活性。使用 PCNB + MPS 系統計算的活化能 (Ea) 也為 46.2 kJ/mol，遠低於最近報導的大多數活化 MPS 研究。 PCNB 也可以在 5 個連續的 HBA 降解週期內重複使用。還通過實驗證據和理論計算全面闡明了 PCNB 和 HBA 降解途徑對 MPS 的激活機制，為開髮用於 HBA 降解的 Co3O4 提供了深入的信息。 |
| 英文摘要 | As 2-hydroxybenzoic acid (HBA) represents a typical pharmaceutical and personal care product (PPCP), constant releasing of HBA into the environment poses threats to the ecology, and thus it is critical to develop effective techniques to remove HBA from water. Recently, sulfate radical (SO4radical dot‒)-based advanced oxidation processes involved with monopersulfate (MPS) activation are proven as effective approaches for eliminating PPCPs from water, and Co3O4 is recognized as a capable catalyst for activating MPS. Therefore, great interests have arisen to develop Co3O4-based catalysts with advantageous morphologies and characteristics for enhancing catalytic activities. Therefore, a special Co3O4-based material is proposed in this work. Through a surfactant-assisted strategy, a cubic Co-MOF is prepared and used as a precursor, which is etched to afford hollow structure, and then transformed into hollow porous Co3O4 nanobox (PCNB). PCNB can exhibit distinct reactive surface with abundant surface oxygen vacancy as well as physical properties in comparison to the commercial Co3O4 NPs (com-Co3O4 NP), thereby leading to the outstanding catalytic activity of PCNB for activating MPS to degrade HBA. The activation energy (Ea) of 46.2 kJ/mol is also calculated using PCNB + MPS system, which is much lower than most of recent reported studies for activating MPS. PCNB could be also reusable over 5 consecutive HBA degradation cycles. The activation mechanism of MPS by PCNB and HBA degradation pathway are also comprehensively elucidated via experimental evidences and the theoretical calculation to offer insightful information of development of Co3O4 for HBA degradation. |
