Ag–Ag₂O nanoparticles were synthesized using Osmium sanctum plant extract. The nanoparticles were sensitized with polythiophene (PTh) and were characterized via scanning electron microscopy with energy dispersive X-ray and elemental mapping, transmission electron microscopy, X-ray diffraction (XRD), Fourier-transform infrared, and UV–vis spectroscopy analyses. The elemental mapping results revealed that the samples were composed of C, S, Ag, and O elements which were uniformly distributed in the nanohybrid. XRD analysis confirmed the crystalline nature of Ag–Ag₂O nanoparticles, and the average particle size was found to be ranging between 36 and 40 nm. The optical band gap of Ag–Ag₂O, PTh, and Ag–Ag₂O/PTh was found to be 2.49, 1.1, 1.5, and 0.68 eV. The catalytic activity of Ag–Ag₂O, PTh, and Ag–Ag₂O/PTh was investigated by degrading paracetamol drug under microwave irradiation. Around 80% of degradation was achieved during 20 min irradiation. All degradation kinetics were fitted to the pseudo-first-order model. A probable degradation pathway for paracetamol degradation was proposed based on liquid chromatography mass spectrometry analysis of degraded fragments.

微波辅助降解植物提取物中聚噻吩敏化的Ag-Ag2O非均相光催化剂对乙酰氨基酚的降解。

Ag-Ag ₂ O纳米粒子是使用O圣地植物提取物合成的。纳米颗粒用聚噻吩（PTh）敏化，并通过具有能量色散X射线和元素图谱的扫描电子显微镜，透射电子显微镜，X射线衍射（XRD），傅立叶变换红外和UV-vis光谱分析进行表征。元素映射结果表明，样品由均匀分布在纳米杂化物中的C，S，Ag和O元素组成。XRD分析证实了Ag-Ag ₂ O纳米颗粒的晶体性质，并且发现平均粒径为36至40 nm。Ag–Ag ₂ O，PTh和Ag–Ag ₂的光学带隙发现O / PTh为2.49、1.1、1.5和0.68eV。通过在微波辐射下降解扑热息痛药物研究了Ag-Ag ₂ O，PTh和Ag-Ag ₂ O / PTh的催化活性。在20分钟的照射过程中，降解率约为80％。所有降解动力学均拟合拟一阶模型。基于液相色谱质谱法对降解片段的分析，提出了扑热息痛降解的可能降解途径。
