During phase...
It is shown that adsorption of the [Au(en)(2)](3+) cationic complex can be successfully employed for deposition gold nanoparticles (1.5 to 3 nm) onto SiO(2) with high metal loading, good dispersion, and small Au particle size. When solution pH increases (from 3.8 10.5), loading in Au/SiO(2) samples proportionally 0.2 5.5 wt %), average size also 1.5 2.4 nm). These effects are explained by increase amount negatively charged sites present on surface, namely, when increases, a higher number...
Gold nanoparticles were deposited on the surface of multiwalled carbon nanotubes (MWNTs) functionalized with aliphatic bifunctional thiols (1,4-butanedithiol, 1,6-hexanedithiol, 1,8-octanedithiol, and 2-aminoethanethiol) through a direct solvent-free procedure. Small gold particles, narrow particle size distribution around 1.7 nm, obtained 1,6-hexanedithiol-functionalized MWNTs. For MWNTs aminothiol, average Au was larger, 5.5 apparently due to coalescence phenomenon. Gatan image filter...
