Here we report on the preparation of a simple, efficient, and recyclable Ag‐dip‐catalyst by dip‐coating process. The dip catalyst was synthesized by dipping the filter papers (Whatman‐40) into pre‐synthesized monodispersed Ag nanoparticles suspensions in toluene. To illustrate the general applicability, the prepared Ag NPs based dip catalyst was tested in different model reactions such as nitro to amine reduction, intramolecular cascade reduction, and degradation of Methyl orange. It displayed high efficiency and excellent reusability. With many remarkable properties, these nanoparticles loaded dip catalyst open new avenues for applications of heterogeneous catalysis in both basic and industrial research.

银纳米颗粒嵌入式滤纸：高效的浸渍催化剂，可用于芳香族硝基苯酚还原，分子内级联反应和甲基橙降解

在这里，我们报道了通过浸涂工艺制备一种简单，高效且可回收的Ag浸催化剂的方法。通过将滤纸（Whatman-40）浸入预先合成的单分散的Ag纳米粒子在甲苯中的悬浮液中来合成浸入催化剂。为了说明一般的适用性，在不同的模型反应中测试了制备的基于Ag NPs的浸入催化剂，例如硝基还原为胺，分子内的级联还原以及甲基橙的降解。它显示了高效率和出色的可重用性。这些具有许多卓越性能的负载纳米粒子的浸渍催化剂为基础和工业研究中的多相催化应用开辟了新途径。
