中文摘要 | 由於廣泛使用的紫外線 (UV) 過濾劑 Ensulizole (ELZ) 已被證明是一種環境激素,因此開發消除 ELZ 的有用技術勢在必行。由於基於SO 4 ·−的氧化技術在處理新興污染物方面具有廣闊的前景,並且鈷(Co)似乎是單過硫酸鹽(MPS)活化的極其有用的催化劑,因此構建有利的MPS活化鈷催化劑至關重要。一種獨特的活化劑源自於特殊的金屬有機骨架([Co]吡嗪[Ni(CN) 4 ]),該骨架被碳化成為由限制在碳奈米球和奈米管中的CoNi合金奈米粒子(NP )組成的奈米團簇,形成CoNi @碳(數控)。這種CNC奈米複合材料將表現出幾個有前途的特性:(1)由於Co是對MPS活化極其有效的金屬,CoNi有望為MPS活化提供優異的性能; (2) CoNi合金的高磁化強度使CNC具有磁可控性; (3) 封裝在碳中的CoNi受到保護,以提高其可重複使用性; (4) CNC的交錯結構也使其顯示出更高的MPS活化活性位點。因此,CNC表現出比傳統MPS多相催化劑Co 3 O 4更強的活化能力。 CNC/MPS 也表現出比文獻更低的 ELZ 降解活化能 (E a ),顯示了 CNC 的優勢。也闡明了 MPS 活化和 ELZ 降解的機制,以進一步了解 MOF 衍生的鈷催化劑消除 ELZ 的過程。 |
英文摘要 | As the widely used ultraviolet (UV) filter, Ensulizole (ELZ), has been proven as an environmental hormone, development of useful techniques for eliminating ELZ is imperative. Since SO4·−-based oxidation technologies are promising for treating emerging contaminants, and cobalt (Co) appears to be an extremely useful catalyst for monopersulfate (MPS) activation, that would be critical to construct advantageous cobaltic catalyst of MPS activation. A unique activator would be derived from a special metal organic framework ([Co]pyrazine[Ni(CN)4]) which is carbonized to become a nanocluster comprised of CoNi alloy nanoparticles (NPs) confined in carbon nanospheres, and nanotubes, forming CoNi@Carbon (CNC). Such a CNC nanocomposite would exhibit several promising properties: (1) as Co is the extremely effective metal for MPS activation, CoNi is expected for offering superior performance for activating MPS; (2) high magnetization of CoNi alloy would equip CNC with a magnetically-controllability; (3) CoNi encapsulated in carbon is guarded to enhance its reusability; (4) the interlaced configurations of CNC also make it to show higher active sites for MPS activation. Thus, CNC exhibits a significantly stronger activating capability than Co3O4, which is the conventional heterogeneous catalyst for MPS. CNC/MPS also displays a lower activation energy (Ea) for ELZ degradation than literatures, showing advantages of CNC. Mechanisms for MPS activation and ELZ degradation were also elucidated to further understand elimination process of ELZ by MOF-derived cobaltic catalysts. |
