Mesostructured porous silica

Mesostructure-fine-tuned and size-controlled hierarchical porous silica nanospheres were synthesized by aldehyde-modified Stöber method in the TEOS–CTAB–NH3·H2O–aldehyde system. The samples were characterized by XRD, N2 adsorption–desorption isotherms, SEM, TEM and TG analysis. The results indicate that the particl This method is based on an organometallic approach consisting in mild decomposition of Ru(COD)(COT) (COD = g4-cycloocta-1,5-diene; COT = g6-cycloocta-1,3,5-triene) embedded inside mesostructured porous silica. The role assigned to the regular channels of MTS is to host and stabilize the metal nanoparticles. The “molecular stencil patterning” technique has been used to optimize at high coverage the distribution of aminopropylsilyl tethers (APS) grafted into the nanochannels of a mesostructured MCM-41 type porous silica. Porous silica‐based materials have burgeoning applications ranging from fillers and additives, to adsorbents, catalysts, and recently therapeutic agents and vaccines in nanomedicine. The preponderance of these materials is made by sol–gel processing wherein soluble silica precursors are reacted to form amorphous networks composed of siloxane bonds.

Short CV

2D XRD patterns of the as-synthesized hex-agonal silica film are shown in: d) recorded by rotation of the film plane starting from A new type of hierarchically porous materials is fabricated by assembling mesoporous nanoparticles via spray drying. Well-dispersed mesostructured silica nanoparticles (MSN), whose particle size distribution was narrow in the range of 20 nm and 50 nm, were prepared by a thermal deposition method. Mesostructured silica waveguide arrays were fabricated with a combination of acidic sol-gel block copolymer templating chemistry and soft lithography.

The preponderance of these materials is made by sol–gel processing wherein soluble silica precursors are reacted to form amorphous networks composed of siloxane bonds. We report that transparent mesostructured silica/gold nanocomposite materials with an interpore distance of 4.1 nm, as-synthesized from a templated sol–gel synthesis method using discotic trinuclear gold(I) pyrazolate complex, were successfully utilized for the fabrication of thin film mesoporous silica nanocomposites containing gold nanoparticles.
