Journal of Electrochemistry
By using Au nanoparticles with a diameter of 55 nm as the core and ascorbic acid as the reductant, Aucore@ Ptshell nanoparticles of controllable Pt shell thickness( 0. 3 ～ 6 nm) were synthesized by controlling the concentration of [PtCl6]2 - ions. The ultraviolet-visible absorption spectrometry,scanning electron microscope ( SEM) ,transmission electron microscope ( TEM) ,high resolution transmission electron microscope ( HRTEM) , and electrochemical cyclic voltammetry were employed to determine surface morphology and structure of Aucore@ Ptshell. With SCN - ion as a probe,the effect of the thickness of the Pt shell on the SERS signals of Aucore@ Ptshell …
