| 中文摘要 | 由於催化加氫被證實是減少水中潛在致癌溴酸鹽的最有用方法之一，因此通常需要使用連續吹掃 H2氣體和貴金屬催化劑，使其在實際實施中不太可行。由於硼氫化鈉(NaBH (HPCO) 通過一步煅燒。所得的 HPCO 與 Co 相比具有顯著的表面氧空位以及結構特性) 也計算為 28.5 kJ/mol。此外，HPCO還表現出很高的催化活性 2 4 ) 是釋放 H 2的潛在替代來源，並且通常需要非貴金屬催化劑（鈷 (Co)）來加速 NaBH 4的水解以更快地產生 H 2，因此 Co-based 之間的組合催化劑和 NaBH 4有利於溴酸鹽加氫。尤其是製備具有高表面積的多孔非均相催化劑更為有利。因此，本研究旨在構建這樣一種新型多孔多相催化劑，用於使用硼氫化鈉還原溴酸鹽。在本文中，採用具有 TMC 配體（CoTMC）的配位骨架作為前體，然後將其轉化為六邊形多孔 Co 3 O 4 NP。重要的是，HPCO 可以在 20 分鐘內將溴酸鹽完全還原為溴化物。使用 HPCO 和 NaBH 4計算的溴酸鹽去除能力達到 781.25 μmol/g，活化能 ( E a用於在各種陰離子存在下還原溴酸鹽。此外，HPCO 還可以重複使用，用於在多個循環中將溴酸鹽還原為溴化物，而催化活性沒有任何顯著變化。這些特徵表明 HPCO 是一種強大且有效的多相催化劑，可用於還原水中的溴酸鹽。 |
| 英文摘要 | As catalytic hydrogenation is validated as one of the most useful approach to reduce a potential carcinogenic bromate in water, the usage of continuous purge H gas and precious metal catalysts are typically required, making it less feasible for practical implementation. Since sodium borohydride (NaBH could be favorable for bromate hydrogenation. Especially, it is even more advantageous to fabricate a porous heterogeneous catalyst with high surface area. Thus, this study aims to construct such a novel porous heterogeneous catalyst for reducing bromate using sodium borohydride. Herein, a Co-coordinated framework with TMC ligand (CoTMC) is employed as precursor, which is then transformed into hexagonal porous Co3O4 (HPCO) via one-step calcination. The resultant HPCO possesses remarkable surficial oxygen vacancies as well as textural properties in comparison with Co is achieved as 781.25 μmol/g, and the activation energy (Ea) is also calculated as 28.5 kJ/mol. Besides, HPCO also exhibits high catalytic activities for bromate reduction in the presence of various anions. Moreover, HPCO could be also reusable for reducing bromate to bromide over multiple-cycles without any remarkable change of catalytic activities. These features indicate that HPCO is a robust and effective heterogeneous catalyst for bromate reduction in water. |
