Short CV

The synthesized LP-MSNs are 100–200 nm in diameter and are composed of cage-like pores organized in a cubic mesostructure. Mesoporous silica nanoparticles are promising materials for various applications, such as drug delivery and catalysis, but the functional roles of surfactants in the formation and preparation of mesostructured silica nanoparticles (MSN-as) remain to be seen. A simple one-pot synthesis process for functionalized mesostructured silica nanoparticles (MSNP) is reported. The novel process demonstrated the possibility to achieve MSNP with a surface area up to 501 m 2.g −1 using a phosphonate based nonsilane precursor such as N, N´-bis [4,6-bis (diethylphosphono)-1,3,5-triazin-yl]-1,2-diaminoethane (ED). A catalyst containing small (ca. 2.5 nm) and crystalline Pt nanoparticles embedded into the walls of a mesostructured silica framework was found to be highly active in alkene hydrosilylation reaching TONs of ca.

This result is remarkable because Pt leaching Pure mesoporous silica nanoparticles were prepared according to published literature procedure. 3 The CTAB surfactant was removed by calcination at 550 °C for 5 h. Attachment of the ICPES linker was accomplished by suspending 100 mg of the calcined particles in 10 mL of a 10 mM solution of ICPES in dry PhMe and refluxing for 12 h under N 2 . 2013-08-21 2014-04-05 Mesostructured cellular foam (MCF) silica is a very interesting new mesoporous silica material.

RESULTS AND DISCUSSION Synthesis of Large Pore Mesoporous Silica Nanoparticles (LP-MSNs). Abstract This study reports an efficient method for the preparation of well-dispersed ruthenium nanoparticles of controlled size loaded into micelle-templated silica (MTS). This method is based on an organometallic approach consisting in mild decomposition of Ru(COD)(COT) (COD = η 4 -cycloocta-1,5-diene; COT = η 6 -cycloocta-1,3,5-triene) embedded inside mesostructured porous silica.
