We demonstrate a novel strategy for the preparation of mesoporous silica-supported, highly dispersed, stable metal and bimetal nanoparticles with both size and site control. The supporting mesoporous silica, functionalized by polyaminoamine (PAMAM) dendrimers, is prepared by repeated Michael addition with methyl acrylates (MA) and amidation reaction with ethylenediamine (EDA) ok? by using aminopropyl-functionalized mesoporous silica as the starting material. The encapsulation of metal nanoparticles within the dendrimer-propagated mesoporous silica is achieved by the chemical reduction of metal-salt-impregnated dendrimer-mesoporous silica by using aqueous hydrazine. The site control of the metal or bimetal nanoparticles is accomplished by the localization of inter-or intradendrimeric nanoparticles within the mesoporous silica tunnels. The size of the encapsulated nanoparticles is controlled by their confinement to the nanocavity of the dendrimer and the mesopore ok? For Cu and Pd, particles locate at the lining of mesoporous tunnels, and have diameters of less than 2.0nm ok? For Pd/Pt, particles locate at the middle of mesoporous tunnels and have diameters in the range of 2.0-4.2nm ok?. The Pd and Pd/Pt nanoparticles are very stable in air, whereas the Cu nanoparticles are stable only in an inert atmosphere.

Metal-organic framework (MOF) coordination polymers have attracted tremendous attention because of their intriguing molecular topologies and their potentially useful ionexchange, adsorption, catalytic, fluorescence, and magnetic properties. [1-7] By taking advantage of the well-defined coordination geometries of metal centers as nodes, the structures of various minerals, such as quartz diamond,[8, 9] perovskite, [10] rutile, [11] PtS, [12, 13] and feldspar,[14] with specific functionalities, have been artificially reproduced by replacing monoatomic anions (O2, S2) with polyatomic organic bridging ligands as linkers. To meet the increasing demand for large-pore frameworks that are suitable for catalyzing reactions of large molecules, successful synthetic strategies for the preparation of large-pore metal-organic polymers with a genuine zeolite topology are still a huge challenge.

Zeolites with uniform micropores have been used as selec-tive catalysts and adsorbents owing to their ability to permit small molecules to enter their pores while leaving larger mole-cules behind, or to allow small molecules to pass through the pores prior to larger molecules.[1] In the past ten years, much effort has been made to develop zeolite membranes for sepa-ration and catalysis applications.[2 11] Zeolite NaA possesses uniform pores of 4 A in size, which falls between the molecu-lar size of O2 and N2 (O2:3.8A

Since Milton synthesized zeolites by means of hydrothermal treatment of alkaline aluminosilicate gels in the 1940s,1 more than a hundred different kinds of zeolites have been synthesized by optimizing synthesis conditions, such as choosing the suitable reactants, gel composition, temperature, etc., and adding suitable organic structure directing agents.2-6 However, zeolites are mostly formed as a fine powder of one to several microns in size, and they contain different kind of faults with high density. The final crystallites are usually aggregated or intergrown within the same families or the same structure as twins.7-12 In those cases, they will show chemical and physical properties different from those expected from perfect periodic structures.13,14

The impetus to the active research on the preparation of silica with regular pores of the diameter in the range of 1-2nm, particularly 1-1.5nm, emanates from their potential application to shape-selective catalysis.1,2 Zeolites UTD-13 and PCH4 are two crystalline aluminosilicates with the largest pores of 0.9-1.0nm. Many efforts to decrease the pore size of mesoporous silica below 2nm have been made to prepare MCM-41 films,5 small pore MCM-41,6,7 SBA-8,8 and SBA-19 with various surfactants as structure-directing agents. Recently, hexagonally ordered silica with X-ray diffraction (XRD) interplanar spacing as small as 2.69nm has been synthesized using mixtures of short double-chain alkylammonium templates.10 Despite limited success, the preparation of microstructured silica with pore diameters of 1-2nm, especially 1-1.5nm, is still difficult to achieve.

A large surface-to-volume ratio is a prerequisite for highly effective catalysts. Making catalysts in the form of nanoparticles provides a good way to achieve the aim. However, agglomeration of nanoparticles during the preparation and utilization of nanocatalysts remains a formidable problem. Here, we present a novel approach in which nano units of catalysts are formed in the matrix of a colloidal carrier, with assistance of a cross-linking agent, and then grow out of the carrier upon calcination at high temperature. This ensures that the catalysts not only do not agglomerate, but also have a low cost and high catalytic efficiency due to the large surface-to-volume ratio and the absence of carbon deposition. The technique is demonstrated by the successful preparation of a binary nanocatalyst that consists of a silica nanoparticle core and a sulfated zirconia (SZ) nanocrystal shell (JML-1). The synthesis was achieved by converting sulfated zirconia (SZ) and silica solutions into a composite gel by means of sol-gel processing in the presence of triethoxysilane as the cross-linking agent, followed by heating at 50℃ and calcining at 550 8C. Relative to other catalysts, such as pure SZ, non-nanodispersed SZ over silica (SZ/SiO2), and zeolites Y, Beta, and ZSM-5, JML-1 exhibits superior catalytic activity in many reactions. For example, the activity of JML-1 in the production of gasoline by alkylation of 1-butene with isobutene remained at 95% or higher after 20 h of reaction and was over 90% after being regenerated five times. In sharp contrast, SZ and SZ/SiO2 give a high activity only for 2h and the initial activity of zeolites Beta and ZSM-5 are about 88 and 60%, respectively. These findings demonstrate that non-agglomerated nanoparticles anchored onto a carrier surface can be prepared and the technique provides a versatile route to new highly effective nanocatalyst systems.
