Colloidal mesoporous silica nanoparticles asymmetrically capped with non-porous phenylsilsesquioxane have been prepared by adding phenyltriethoxysilane to an aqueous dispersion of mesostructured silica-surfactant composite nanoparticles. The integration of colloidal stability, mesoporosity and the Janus structure is quite promising for materials design applicable in various fields, including ca...

Oxygen-deficient luminescent mesoporous silica nanoparticles with uniform morphology/size and integrated mesoporosity-luminescent property in a single nanoparticle are successfully synthesized by a bottom-up self-assembly route followed by a post-calcination process, and can be used to facilely load/deliver drugs into cells and luminescently image cells.

Highly crystalline rutile with a specific surface area as high as 280 m(2) g(-1) and well-connected uniform mesoporosity has been synthesized by rigid templating using commercial, low-cost polyether block amide. This general, simple synthesis route for high surface-area mesoporous nanocrystalline oxides and nanocomposite membranes is important for catalysis, sensors, energy storage, solar cells...

We report a facile one-pot synthesis of hierarchically porous scaffolds, with independent control over nanoparticle mesoporosity and scaffold macroporosity. Our technique combines the chemistry of mesoporous silica nanoparticles with the control afforded by dynamic templating of surfactant mesophases. These materials are readily functionalizable and allow controllable spatial variation in macro...

The sequential fluorination-alkaline treatment protocol has been applied for the tailoring of siliceous ZSM-5 zeolite. original spontaneous growth mesoporosity in alkaline medium is altered due to antecedent fluorination step. outcome demonstrated by apparent delay growth, whose essential duration well-defined therefore extended from 30 min 60 min. A low level decelerates whereas a high enables...

Herein, the effect of various treatments subjected to FAU zeolites introduce mesoporosity has been examined on their efficiency as catalyst in cyclisation O-aryl 3-arylpropynoic acid ester its corresponding coumarin. The addition bio-sourced lignin residues alkaline desilication treatment induced generation supplementary mesoporosity, thus offering an optimal micro- and mesopores combination wi...

We describe in this paper the development of plugged hexagonal templated silicas (PHTS) which are hexagonally ordered materials, with internal microporous silica nanocapsules; they have a combined micro- and mesoporosity and a tuneable amount of both open and encapsulated mesopores and are much more stable than other tested micellar templated structures.

The in situ formation of sub-100 nm solid frameworks stabilized against dissolution by the addition of nanoseeds allows the facile and controllable synthesis of TiO(2) (anatase) mesocrystalline structures with spherical shape, mesoporosity and sizes between 50 and 70 nm. As an example of their multifunctionality, these structures show good capabilities for enzyme immobilization and adequate pho...
