Ag2S nanoparticles were prepared by a solvothermal process via reaction of Ag(NO3) and a new sulfuring agent from class of thio Schiff-base (2-(benzylidene amino) benzenethiol (C13H11NS)) in presence of various solvents. Spectra such as X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SEAD), ultraviolet-visible (UV-Vis) spectroscopy, thermo gravimetric-differential thermal analysis (TG-DTA), and Fourier transform Infrared (FT-IR) employed to characterize the synthesized products. Results of this paper indicate that shape and size of the silver sulfide can be controlled by means of setting certain reaction parameters such as the reaction temperature, presence of surfactant, and type of solvent. Silver sulfide nanoparticles with different morphology and size successfully prepared. In addition, the growth mechanisms of the Ag2S nanoparticles discussed preliminarily.
通过溶剂热法,使硝酸银(Ag(NO₃))与硫代席夫碱类新型硫化剂(2-(苄叉氨基)苯硫酚(C₁₃H₁₁NS))在各种溶剂存在下反应,制备了硫化银(Ag₂S)纳米颗粒。采用X射线衍射(XRD)、透射电子显微镜(TEM)、选区电子衍射(SEAD)、紫外可见(UV-Vis)光谱、热重-差热分析(TG-DTA)和傅里叶变换红外(FT-IR)等光谱对合成产物进行表征。本文结果表明,通过设定某些反应参数,如反应温度、表面活性剂的存在和溶剂类型,可以控制硫化银的形状和尺寸。成功制备了具有不同形貌和尺寸的硫化银纳米颗粒。此外,还初步讨论了Ag₂S纳米颗粒的生长机制。
