Cyanex 301修饰Ag2S纳米粒子的制备及表征
Preparation and Characterization of Ag2S Nanoparticles Modified by Cyanex 301
【摘要】 在醇/水混合介质中,用共沉淀法制备了Cyanex 301(二(2,4,4-三甲基戊基)二硫代膦酸)修饰的Ag2S纳米粒子。用XRDI、R、TEM、UV-Vis和TG等表征了粒子的形貌与结构。结果表明,将表面吸附了Cyanex 301的纳米粒子分散到有机溶剂中能形成稳定的含硫化银纳米粒子的有机流体,其负载量随溶剂极性的增大而降低。
【Abstract】 Oil-soluble Ag2S nano-particles modified by Cyanex 301 have been prepared in the solvent mixture of ethanol and water.The fluids containing Ag2S nano-particles are obtained after dispersing the nano-particles into organic solvents.The nano-particles are characterized by XRD,IR,TEM, UV-Vis and TG.The loading concentration decreases with the increase of the solvent polarity.
