| 中文摘要 | 金屬有機框架 (MOF) 是一類很有前途的金屬催化劑，可用於減少含氮污染物 (NCC)，例如 4-硝基苯酚 (4-NP)。然而，大多數涉及 MOF 還原 4-NP 的研究使用細粉末形式的貴金屬，使得這些粉末狀貴金屬基 MOF 不切實際且不便於實際應用。因此，開發可以結合到宏觀和多孔載體中以方便應用的非貴金屬 MOF 將是至關重要的。在此，本研究建議開發一種複合材料，它結合了宏觀/多孔載體的優勢特徵和 MOF 的納米級功能。特別是，泡沫銅 (CF) 被選為宏觀多孔介質，其被納米花結構的 CoO 覆蓋，以增加用於生長鈷 MOF ZIF-67 的表面。所得複合材料由用 ZIF-67 裝飾的 CoO 納米花覆蓋的 CF 組成，形成分層的 3D 結構催化劑，使這種 ZIF-67@Cu 泡沫（ZIF@CF）成為還原 4-NP 和其他 NCC 的有前途的催化劑。因此，ZIF@CF 可以很容易地將 4-NP 還原為 4-AP，其 Ea 顯著低於報告值 20kJ/mol。 ZIF@CF 可以重複使用 10 次以上，並且對 4-NP 還原仍然非常有效。 ZIF@CF 還可以有效地減少其他 NCC，如 2-硝基苯酚、3-硝基苯酚、亞甲藍和甲基橙。 ZIF@CF 可用作催化過濾器，通過將 NCC 溶液通過 ZIF@CF 來實現過濾式還原 NCC，從而快速方便地減少 NCC。 ZIF@CF 的多功能和有利的催化活性證明 ZIF@CF 是一種用於 NCC 還原處理的有前途且實用的多相催化劑。 |
| 英文摘要 | Metal Organic Frameworks (MOFs) represent a promising class of metallic catalysts for reduction of nitrogen-containing contaminants (NCCs), such as 4-nitrophenol (4-NP). Nevertheless, most researches involving MOFs for 4-NP reduction employ noble metals in the form of fine powders, making these powdered noble metal-based MOFs impractical and inconvenient for realistic applications. Thus, it would be critical to develop non-noble-metal MOFs which can be incorporated into macroscale and porous supports for convenient applications. Herein, the present study proposes to develop a composite material which combines advantageous features of macroscale/porous supports, and nanoscale functionality of MOFs. In particular, copper foam (CF) is selected as a macroscale porous medium, which is covered by nanoflower-structured CoO to increase surfaces for growing a cobaltic MOF, ZIF-67. The resultant composite comprises of CF covered by CoO nanoflowers decorated with ZIF-67 to form a hierarchical 3D-structured catalyst, enabling this ZIF-67@Cu foam (ZIF@CF) a promising catalyst for reducing 4-NP, and other NCCs. Thus, ZIF@CF can readily reduce 4-NP to 4-AP with a significantly lower Ea of 20 kJ/mol than reported values. ZIF@CF could be reused over 10 cycles and remain highly effective for 4-NP reduction. ZIF@CF also efficiently reduces other NCCs, such as 2-nitrophenol, 3-nitrophenol, methylene blue, and methyl orange. ZIF@CF can be adopted as catalytic filters to enable filtration-type reduction of NCCs by passing NCC solutions through ZIF@CF to promptly and conveniently reduce NCCs. The versatile and advantageous catalytic activity of ZIF@CF validates that ZIF@CF is a promising and practical heterogeneous catalyst for reductive treatments of NCCs. |
