Preparation of MFI type zeolite with hierarchical pores system as new supports for deposition of metal clusters
A method of preparation of high-silica zeolite crystals (MFI type) containing meso-/macrovoids is described. The modification of the crystals was obtained during the hydrothermal synthesis with the use of different meso-/macro matrices like mono- and polydispersed carbon particles. Presence of the meso-/macrovoids in the crystals was directly proved with TEM analysis. The modified MFI zeolite crystals could be successfully used for the deposition of highly dispersed metal (Pd) phase when the impregnation with a metal salt solution (the incipient wetness technique) followed by the reduction in an H2/N2 stream was applied. The deposition of small (2-4 nm) Pd clusters inside the meso-/macrovoids was proved with HRTEM and STEM/HAADF technique. The deposition of Pd in the crystals limited the size and number of bigger metal particles deposited at the outer surface.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Application In Synthesis of Tetrapropylammonium bromide, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1941-30-6
