Au nanoparticles (NPs) were uniformly dispersed on ETS-10 titanosilicate using the cation exchange procedure and [Au(NH3)(4)](NO3)(3) complex as the gold source. [Au(NH3)(4)](3+) cations were first introduced inside ETS-10 micropores, ligands were then released, Au3+ was reduced to Au+ forming electron-deficient Au clusters, and finally aggregation to Au NPs occurred. In comparison to the incipient-wetness and deposition-precipitation methods, the ion-exchange led to greater activity of the Au NPs in the oxidation of 1-phenylethanol by oxygen.
