چکیده
This article demonstrates preparation of metal functionalized zeolite catalysts via a new homogeneous solution pathway enabled by the recently reported exfoliation MWW into unilamellar nanosheets. The is carried out mixing solutions exfoliated monolayers and Pt nanoparticles with initial size ca 3 nm isolation such hybrid freeze-drying. Optionally, layer were purified dialysis prior to solution, which turned be beneficial for quality textural characteristics. However, catalytic performance in model reaction – 3-nitrotoluene hydrogenation, was mostly determined level, i.e. at least 0.3%, less affected apparent final support. revealed agglomeration from roughly between 5 10 nm.

One-pot synthesis of MWW zeolite nanosheets using a rationally designed organic structure-directing agent.
A new material MIT-1 comprised of delaminated MWW zeolite nanosheets is synthesized in one-pot using a rationally designed organic structure-directing agent (OSDA). The OSDA is comprised of a hydrophilic head segment that resembles the OSDA used to synthesize the zeolite precursor MCM22(P), a hydrophobic tail segment that resembles the swelling agent used to swell MCM22(P), and a di-quaternary ...
متن کاملPhotochemical preparation of silver nanoparticles supported on zeolite crystals.
A facile and rapid photochemical method for preparing supported silver nanoparticles (Ag-NPs) in a suspension of faujasite type (FAU) zeolite nanocrystals is described. Silver cations are introduced by ion exchange into the zeolite and subsequently irradiated with a Xe-Hg lamp (200 W) in the presence of a photoactive reducing agent (2-hydroxy-2-methylpropiophenone). UV-vis characterization indi...
متن کاملSupported Zeolite Beta Layers via an Organic Template-Free Preparation Route.
Layers of high silica zeolites, synthesized with an organic structure directing agent (OSDA) and grown onto porous support structures, frequently suffer from the thermal stress during the removal of OSDA via the calcination process. The different thermal expansion coefficients of the zeolite and the support material, especially when stainless steel is used as a support, causes enormous tension ...
متن کاملEvolution of ZnS Nanoparticles via Facile CTAB Aqueous Micellar Solution Route: A Study on Controlling Parameters
Synthesis of semiconductor nanoparticles with new photophysical properties is an area of special interest. Here, we report synthesis of ZnS nanoparticles in aqueous micellar solution of Cetyltrimethylammonium bromide (CTAB). The size of ZnS nanodispersions in aqueous micellar solution has been calculated using UV-vis spectroscopy, XRD, SAXS, and TEM measurements. The nanoparticles are found to ...
