摘　　要：构建高效稳定的刚果红(CR)降解催化剂体系对人类健康和环境保护至关重要.本文通过简便的水热合成技术,以CoCl 2·6H_(2)O为无机金属中心、2,2′-联吡啶-5,5′-二羟基(BPDCH_(2))为有机配体,开发制备了[Co(2,2′-bipyridine-5,5′-dicarboxylato)(H_(2)O)]·(H_(2)O)催化剂.探讨通过钴基金属有机骨架(Co-MOF)活化过一硫酸盐(PMS)对CR催化降解性能的影响.在温和的实验条件下,Co-MOF/PMS复合物对CR的降解效率达到了100%.结合淬灭实验和液相色谱/飞行时间质谱定量分析,阐明了反应产生的降解中间产物和副产物,同时推测出PMS的活化过程和CR的降解途径.研究彰显了Co-MOF/PMS复合物作为环境净化高效催化剂的卓越潜力,标志着其在CR降解及废水处理技术领域取得了重要进展.The construction of highly efficient and stable catalyst system for Cong red(CR)degradation is crucial on human health and environmental protection.Herein,a[Co(2,2′-bipyridine-5,5′-dicarboxylato)(H_(2)O)]·(H_(2)O)was developed and prepared by using CoCl 2·6H_(2)O as inorganic metal center with organic ligands 2,2′-Bipyridine-5,5′-dicarboxylic acid(BPDCH_(2))via a facile hydrothermal synthesis technique.An exploration of cobalt-based metal-organic framework(Co-MOF)on the catalytic degradation performance of CR via activation of peroxymonosulfate(PMS)was undertook.The Co-MOF/PMS complex demonstrated a peak efficacy of 100%in degradation under favorable experimental conditions.Notably,quenching assays coupled with liquid chromatography/quantitative time-of-flight mass spectrometry deftly elucidated the degradation intermediates and byproducts emanating from the reaction,concurrently delineating the activation cascade of PMS and the degradation pathway of CR.The research demonstrates the exceptional potential of the Co-MOF/PMS composite as an efficient catalyst for environmental purification,marking significant progress in the field of CR degradation and wastewater treatment technologies.
