Abstract
Au nanoparticles (NPs) were uniformly dispersed on ETS-10 titanosilicate using the cation exchange procedure and [Au(NH3)4](NO 3)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.
