| Abstract: | By utilizing adsorption phase synthesis (APS), Au nanoparticles were prepared on the surface of SiO2 with or without modification by Ni(OH)2. TEM, XRD, and UV‐vis were employed to characterize the morphology of Au particles on the surface of two kinds of supports. The results showed that the average size of Au particles on the SiO2 surface modified by Ni(OH)2 was less than 5 nm. Due to high surface isoelectric point, Au particles formed in the adsorption layer were prone to distribute on the surface of SiO2 modified by Ni(OH)2. With content of Ni(OH)2 in samples increasing, more Au particles with small size appeared on the support surface. |
