Abstract:

Au particles supported on TS-1 are prepared by deposition precipitation method with ammonium salt solution as Promoter. FT-IR and Si-29 NMR indicate that the modifications do not destroy the MFI structure of TS-1 and retain the tetra-coordination skeleton titanium. DFT and UV-Vis analysis show that under the transition from [AuCl4](-) to [AuCl4-x(NH3)(x)](x-1) (x = 0-2) in the preparation process, NH3 enhance the attraction of gold precursors and supports (the gold capture effectivity is 94.5%), and C2O42- reduces the gold complex into AuNPs (1.14 nm).
