Catalytic degradation of organic water pollutants has emerged as a cost- and energy-effective technique to treat wastewater. In this work, new silver and magnetite nanoparticles (NPs) were prepared with a protic poly(ionic liquid) (PIL) based on a quaternized diethylethanolamine cation combined with 2-acrylamido-2-methylpropane sulfonate-co-vinylpyrrolidone (QAMPSA/VP) as a capping and a reducing agent. The morphology, particle size, surface charge, thermal stability, and magnetic properties of QAMPS/VP-Ag and Fe3O4 NPs were investigated to determine the efficiency of the PIL as a reducing and a capping agent to protect the produced NPs from oxidation or thermal degradation. The activation energy, enthalpy, and entropy of the catalytic degradation of the cationic methylene blue (MB) dye in the presence of QAMPS/VP-Ag and Fe3O4 NPs were determined. The data elucidated that MB was completely degraded in 8 min in the presence of QAMPS/VP-Fe3O4 NPs as a Fenton oxidation catalyst. Moreover, their good magnetic properties allowed their easy separation and reuse for five cycles without losing their magnetic or catalytic properties.

使用基于季铵化二烷基乙醇胺和2-丙烯酰胺基-2-甲基丙烷磺酸盐-共乙烯基吡咯烷酮的聚离子液体官能化的银和磁铁矿纳米粒子对亚甲基蓝进行催化降解。
催化降解有机水污染物已成为处理废水的一种经济高效的技术。在这项工作中，基于季铵化的二乙基乙醇胺阳离子与2-丙烯酰胺基-2-甲基丙烷磺酸盐-共乙烯基吡咯烷酮（QAMPSA / VP）结合的质子性聚离子液体（PIL），制备了新的银和磁铁矿纳米粒子（NPs）作为封端剂和还原剂。研究了QAMPS / VP-Ag和Fe3O4 NP的形态，粒度，表面电荷，热稳定性和磁性能，以确定PIL作为还原剂和封端剂的效率，以保护生产的NP免受氧化或热降解。 。确定了在存在QAMPS / VP-Ag和Fe3O4 NPs的情况下，阳离子亚甲基蓝（MB）染料的催化降解的活化能，焓和熵。数据表明，在作为Fenton氧化催化剂的QAMPS / VP-Fe3O4 NP存在下，MB在8分钟内被完全降解。此外，它们良好的磁性能使其易于分离和重复使用五个循环，而不会损失其磁性能或催化性能。
