Abstract An eco-friendly catalyst system was synthesized using three step reaction. The Cu nanoparticles bridged aminoclay catalyst was analyzed using various analytical techniques. The structure of the catalyst was confirmed by FTIR and XRD. The synthesized catalyst system was used for the reduction of p-nitrophenol (NP), Cr(VI), and fluorescein (Flur) dye individually, as well as in their mixture forms. The kapp value was computed to access the efficiency of the catalyst. The results indicated that the kapp value of the individual system is higher than that of the mixture systems due to the absence of the complex formation reaction. The catalytic performance of the catalyst was also tested for the Schiff base (SB) formation between poly(ethyleneglycol) (PEG) and aniline (ANI) in an oxygen atmosphere. The 1H-NMR spectroscopy result indicates that the present catalyst system produced 86% yield.

用于催化应用的氨基粘土的结构改性

摘要 采用三步反应合成了一种环保型催化剂体系。使用各种分析技术分析了Cu纳米颗粒桥连氨基粘土催化剂。通过FTIR和XRD确定了催化剂的结构。合成的催化剂体系用于分别还原对硝基苯酚 (NP)、Cr(VI) 和荧光素 (Flur) 染料，以及它们的混合物形式。计算 kapp 值以获取催化剂的效率。结果表明，由于不存在络合物形成反应，单个系统的 kapp 值高于混合系统的 kapp 值。还测试了催化剂的催化性能，用于在氧气氛中聚（乙二醇）（PEG）和苯胺（ANI）之间形成席夫碱（SB）。
