4、Growth Method(3-Step)910113.Machanism of Au NR GrowthFor 3-step seed growth method,(A)CTAB is a capping agent rather than soft template;(B)Au(I)prefers to add at the tips due to a prevailing electric field effect.Adv.Funct.Mater.2004,14,5719 J.Phys.Chem.B.2005,109,138577012For Ag assistant growth me
5、thod,Contradiction?13In situ characterizingTimeresolved UVvis absorbance spectroscopySmall angle X-ray scattering(SAXS)X-ray absorption spectroscopy(XANES)Liquid cell TEM,cryo-TEM,AFMThe Aun+depletion rate is very sensitive to pH near the pKa of AA;Ag+prevents Au NR from overgrowing;The reduction of Au happens on the surface of Au NR;14Thanks!
