| 中文摘要 | 由於5-磺基水楊酸（SFA）已經越來越多地釋放到環境中，SO 4 自由基點-使用過硫酸氫鉀為基礎的氧化過程已被視為有用的方法，以消除SFA。由於Co 3 O 4是用於OX活化的有前途的材料，因此四種具有不同形態的3D Co 3 O 4催化劑包括Co 3 O 4 -C（帶立方體），Co 3 O 4 -P（帶板），Co 製造3 O 4 -N（帶針）和Co 3 O 4 -F（帶花狀結構）以激活OX降解SFA。特別是Co 3O 4 -F不僅具有最高的表面積，而且具有豐富的Co 2+和更多的反應性表面，這使Co 3 O 4 -F成為用於OX活化降解SFA 的最有利的3D Co 3 O 4催化劑。還研究了這種3D Co 3 O 4 / OX引起的SFA機理，並闡明了相應的SFA降解途徑。Co 3 O 4催化劑的催化活性可以與與特定形態相關的物理和化學性質相關，以提供有關3D Co 3 O 4設計的見解催化劑，用於OX的技術，以降解新興污染物，例如SFA。 |
| 英文摘要 | Since 5-sulfosalicylic acid (SFA) has been increasingly released to the environment, SO4radical dot−-based oxidation processes using Oxone have been considered as useful methods to eliminate SFA. As Co3O4 has been a promising material for OX activation, the four 3D Co3O4 catalysts with distinct morphologies, including Co3O4-C (with cubes), Co3O4-P (with plates), Co3O4-N (with needles) and Co3O4-F (with floral structures), are fabricated for activating OX to degrade SFA. In particular, Co3O4-F not only exhibits the highest surface area but also possesses the abundant Co2+ and more reactive surface, making Co3O4-F the most advantageous 3D Co3O4 catalyst for OX activation to degrade SFA. The mechanism of SFA by this 3D Co3O4/OX is also investigated and the corresponding SFA degradation pathway has been elucidated. The catalytic activities of Co3O4 catalysts can be correlated to physical and chemical properties which were associated with particular morphologies to provide insights into design of 3D Co3O4-based catalysts for OX-based technology to degrade emerging contaminants, such as SFA. |
