Herein, a mild and efficient method for synthesis of highly stable palladium nanoparticles (PdNPs) on Aristolochia Olivieri (AO) extract as a support and reducing agent is described. Investigation of catalytically activity of obtained catalyst (AO@PdNPs) was performed for the reduction of nitroaromatic compounds. Of note are the functional group tolerance, fast rate, and the ability to apply a scope of nitro compounds (up to 30). The synthesized catalyst was characterized with UV−visible spectra, FE-SEM, EDS, XRD, AAS, FT-IR, and TEM techniques. The corresponding amine product was obtained excellent to high yields. The catalytic activity of AO@ PdNPs for the hydrogenation of 4-methyl-2-nitroaniline and 4-methoxy-2-nitroaniline was pursued by UV-visible spectroscopy which presented excellent activity of catalyst.

在此，描述了一种以马兜铃 (AO) 提取物为载体和还原剂合成高度稳定的钯纳米粒子 (PdNPs) 的温和有效的方法。对所得催化剂（AO@PdNPs）的催化活性进行了研究，以还原硝基芳族化合物。值得注意的是官能团耐受性、速度快以及应用范围广泛的硝基化合物（最多 30 个）的能力。合成的催化剂用紫外-可见光谱、FE-SEM、EDS、XRD、AAS、FT-IR 和 TEM 技术表征。以极好至高产率获得了相应的胺产物。AO@PdNPs 对 4-甲基-2-硝基苯胺和 4-甲氧基-2-硝基苯胺加氢的催化活性是通过紫外-可见光谱研究的，表现出优异的催化剂活性。
