Highly ordered mesoporous polymer−silica and carbon−silica nanocomposites with interpenetrating networks have been successfully synthesized by the evaporation-induced triconstituent co-assembly method, wherein soluble resol polymer is used as an organic precursor, prehydrolyzed TEOS is used as an inorganic precursor, and triblock copolymer F127 is used as a template. The formation of mesostructured silica was investigated using acidic conditions with tetraethoxysilane (TEOS) as the silica precursor and cetyltrimethylammonium bromide (CTAB) as the structure directing agent.

https://doi.org/10.1039/C5NR04465K Isolated and purified organosolv eucalyptus wood lignin was depolymerized at different temperatures with and without mesostructured silica catalysts (i.e., SBA-15, MCM-41, ZrO2-SBA-15 and ZrO2-MCM-41). It was found that at 300°C for 1h with a solid/liquid ratio of 0.0175/1 (w/v), the SBA-15 catalyst … Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm.

The radial dependence of the spatial mesostructure of - DiVA Portal

In the first part of the work, mesostructured materials with expanded pores have been produced using a well established aerosol-based method as well as the newly developed emulsion and solvent evaporation (ESE) method. Abstract. Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder.

Unlike the organic micro/nanocrystals prepared using an emerging reprecipitation method, a novel method of embedding 1-pyrenecarboxaldehyde dots (PycDs) into a mesostructured silica xerogel (PycDs@MSX) for use as electrochemiluminescence (ECL) emitters was first proposed to achieve an extremely strong ECL response, with peroxydisulfate (S 2 O 8 2-) used as a coreactant. Although silica nanoparticles are used as building blocks in nature and synthetic mesostructures, the influence of nanoparticle characteristics on the assembly and disassembly of mesostructured 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. 105.
