| 中文摘要 | 在此，發展了一系列裝飾在源自廢棄物的Mobil Composition of Matter No. 41 (MCM-41)上的CoFe 2 O 4系列。將 MCM-41 用作 CoFe 2 O 4 (CFMCM)的載體可提供分散催化劑和吸附浸出金屬的雙重功能，從而實現卓越的性能和穩定性。 CFMCM 用作過一硫酸鹽 (PMS) 活化劑，用於去除環丙沙星(CIP)，顯示含有 11 wt% CoFe 2 O 4的 CFMCM (CFMCM-11) 具有最高的性能 ( k app = 0.17 min -1 )。增加催化劑負載量和 PMS 用量對 CIP 降解有正面貢獻。此催化劑可重複使用至少3次，且沒有明顯的金屬浸出（<35 µg/L），顯示其穩定。使用清除劑對主要活性物質的分析表明，SO 4 •−是主要活性物質，而 HO •發揮次要作用。 SO 4 •−和HO •由Co 2+ /Co 3+和Fe 2+ /Fe 3+之間的氧化還原轉變產生。基於確定的中間體，提出了由哌嗪環氧化和脫羧反應組成的 CIP 降解途徑。總的來說，這項研究表明，廢棄物衍生材料可以作為開發環境應用催化劑策略的一部分。 |
| 英文摘要 | Herein, a series of CoFe2O4 decorated on waste-derived Mobil Composition of Matter No. 41 (MCM-41) was developed. Incorporation of MCM-41 as a support for CoFe2O4 (CFMCM) provides dual functionality to disperse the catalyst and adsorb leached metal, leading to remarkable performance and stability. The CFMCM was used as a peroxymonosulfate (PMS) activator for ciprofloxacin (CIP) removal indicating that CFMCM with 11 wt% CoFe2O4 (CFMCM-11) had the highest performance (kapp = 0.17 min−1). Increasing the catalyst loading and PMS dosage contributed positively to the CIP degradation. The catalyst can be reused at least 3 times without significant metal leaching (<35 µg/L) showing that it is stable. Analysis of the dominant reactive species using scavengers revealed that SO4•− was the major reactive species while HO• played a minor role. The SO4•− and HO• were generated from the redox transition between Co2+/Co3+ and Fe2+/Fe3+. Based on the intermediates identified, the CIP degradation pathways consisting of piperazine ring oxidation, and decarboxylation reactions were proposed. Overall, this study shows that the waste-derived materials can be integrated as part of the strategy to develop catalysts for environmental applications. |
