제안 방법
- In this study, we investigated simple and economic preparation route based on impregnation method to make silica-gold composite particles with high yield and economical price. The obtained Silica-gold composite particles were characterized through FE-SEM and XRD.
- To investigate formation and morphological properties of composite particles, field emission scanning electron microscopy (FE-SEM, JEOL JSM-6700F) was used. To verify the formation of gold, X-ray diffractometry measurement was performed with a Rigaku D/MAX-3C x-ray diffractometer. The incident wavelength was Cu Kα1 = 1.
- To investigate the effect of precursor on the formation of silica-gold composite particles, two different precursor conditions were examined: gold ions(No2 in table 1) and gold-PVP complexes(No3 in table 1). The concentration of gold in composite particles fixed to 1.
대상 데이터
- Hydrogentetrachloroaurate(Ⅲ) hydrate(HAuCl4․ nH2O,n=3.7,Kojima Chemicals) and polyvinylpyrrolidone (PVP, K-15, Mw10,000, Junsei Chemical Company ,Japan) were purchased and used. Silica particles were suggested and provided by Quick&Safe.

- Silica-gold composite particles were prepared by impregnation method. When spherical silica particles and PVP and hydrogentetrachloroaurate (Ⅲ) hydrate aqueous solution were used as support material and precursor solution, silica-gold composite particles with light pink color successfully obtained.
