Ordered porous materials with unique pore structures and pore sizes in the mesoporous range (2-50 nm) have many applications in catalysis, separation and drug delivery. Extensive research has resulted in mesoporous materials with one-dimensional, cage-like and bi-continuous pore structures. Three families of bi-continuous mesoporous materials have been made, with two interwoven but unconnected ...

A novel synthesis method for ordered mesoporous carbons is presented. The inverse replication of a silica template was achieved using the carbonization of sucrose within mesoporous KIT-6. Instead of liquid acid etching, as in classical nanocasting, a novel dry chlorine etching procedure for template removal is presented for the first time. The resultant ordered mesostructured carbon material ou...

In this study, highly ordered mesoporous silica material (SBA-15) functionalized with Diethyl 2 - (9 -fluorenyl) malonate as a flourophore is reported. The anchoring of flourophores to the hydroxyl group on SBA-15 surface was done with post synthesis method. The obtained materials were characterized by small and wide angle X-ray diffraction, N2 adsorption–desorption, Fourier transform infrared ...

Self-assembled mesoporous structures with well-ordered nanoscale channels could be used in applications such as molecular separation, nano-optics, molecular electronics, nanomedicine and catalysis. However, the domain sizes that can be created in such systems are limited by our lack of a detailed understanding of the relevant growth processes. Here we report the real-time observation of domain ...

(Chemical) processes under spatial confinements are important for a number of areas, as for instance in catalysis (chemistry) or enzymatic reactions (biology). The role of the spatial restriction parallel to the functional interactions in these systems is hard to trace. Ordered mesoporous silica materials are ideal to provide a multiplicity of parallel, just nanometer-large, well-defined confin...

In this contribution, an effective and soft method for removal of template from nanochannels of mesoporous silica (MCM-41) is proposed. This method is based on chemically-modified solvent extraction which enhanced by means of an auxiliary organic compound, i.e. benzene sulfonamide. Template removal was performed in soft condition, i.e. in the presence of diluted sulfuric acid and at ambient tem...

The purpose of this study was to improve our understanding of the molecular organization of hydrophobic guest molecules in the presence of co-adsorbed water inside SBA-15 ordered mesoporous silica material. Understanding this adsorption competition is essential in the development of applications of controlled adsorption and desorption. The poorly water soluble drug compound itraconazole and the...

Introduction Advanced applications often require carbons with high surface area and hierarchical porous structures. In response to this demand some efforts have been undertaken to create materials, which effectively combine the properties of both activated carbons (high surface area) and ordered mesoporous carbons (tunable and well-developed porosity). While there are activation methods, which ...
