2,3,5,6-Tetrakis-(morpholinomethyl) hydroquinone (TMMH) was used as a reducing agent to synthesize spherical shaped silver nanoparticles in water-ethanol medium without using any stabilizing and capping agents. The reducing agent TMMH is prepared by Mannich-type reaction method and (1)H NMR, (13)C NMR and FT-IR spectroscopy techniques were used to characterize the compound (TMMH). The nature of bonding, structural and optical properties of the final product were analyzed using different techniques such as UV-Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). The interaction between silver and reducing agent was confirmed by using FTIR analysis. The final product obtained showed higher crystallinity with cubic structure and an average crystalline size of about 20 nm. The results revealed that it is possible to synthesize crystalline Ag nanoparticles using organic compound as reducing agent.
2,3,5,6-四(吗啉甲基)对苯二酚（TMMH）被用作还原剂，在水-乙醇介质中合成了球形银纳米粒子，而无需使用任何稳定剂和封端剂。还原剂 TMMH 通过曼尼希反应方法制备，并用（1）H NMR、（13）C NMR 和 FT-IR 光谱技术对化合物（TMMH）进行了表征。使用不同的技术，如紫外-可见光谱、X 射线衍射（XRD）、扫描电子显微镜（SEM）和傅里叶变换红外光谱（FTIR），对最终产物的键合性质、结构和光学性质进行了分析。通过 FTIR 分析证实了银和还原剂之间的相互作用。所得的最终产物具有更高的结晶度，呈立方结构，平均晶粒尺寸约为 20nm。结果表明，使用有机化合物作为还原剂可以合成结晶 Ag 纳米粒子。
