Amino-functionalized SBA-15 type mesoporous silicas having unique hexagonal platelet morphologies with short channels (100-300 nm) running parallel to the thickness of the nanostructured hexagonal platelet type morphologies have been directly synthesized by co-condensation of aminopropyltriethoxysilane (APTES) and sodium metasilicate as a silica source in the presence of Pluronic P123 triblock ...

Mesoporous SBA-15 functionalized with aggregation-induced emission (AIE) luminogens serves as an efficient and recyclable fluorescent sensor for the detection of picric acid (PA), with a quenching constant of up to 2.5 × 10(5) M(-1) in a water solution, presenting a new model for the supersensitive detection of explosives.

A facile method to construct chiral organoiridium-functionalized periodic mesoporous organosilica is developed. The heterogeneous catalyst displays excellent catalytic efficiency in the enantioselective reduction of α-cyanoacetophenones and α-nitroacetophenones in aqueous medium because of the hydrophobic nature and uniformly distributed active iridium species. The catalyst could be convenientl...

Mesoporous ZnS-NiS composites are prepared via ion- exchange reactions using ZnS as the precursor. The prepared mesoporous ZnS-NiS composite materials have large surface areas (137.9 m(2) g(-1)) compared with the ZnS precursor. More importantly, the application of these mesoporous ZnS-NiS composites as nonenzymatic glucose sensors was successfully explored. Electrochemical sensors based on meso...

A hierarchical zeolite CaA with microporous, mesoporous and macroporous structure was hydrothermally synthesized by a ”Bond-Blocking” method using organo-functionalized mesoporous silica (MS) as a silica source. The characterization by XRD, SEM/TEM and N2 adsorption/desorption techniques showed that the prepared material had well-crystalline zeolite Linde Type A (LTA) topological structure, mic...

In this study, we prepared a mesoporous carbon with hexagonally packed mesopores through evaporation-induced self-assembly (EISA)—with the diblock copolymer poly(ethylene oxide-b-ε-caprolactone) (PEO-b-PCL) as the template (EO114CL84), phenolic resin as the carbon precursor, hexamethylenetetramine (HMTA) as the curing agent, and star octakis-PEO-functionalized polyhedral oligomeric silsesquioxa...

A new hybrid photoelectrochemical photoanode is developed to generate H2 from water. The anode is composed of a TiO2 mesoporous frame functionalized by colloidal core@shell quantum dots (QDs) followed by CdS and ZnS capping layers. Saturated photocurrent density as high as 11.2 mA cm-2 in a solar-cell-driven photoelectrochemical system using near-infrared QDs is obtained.

The highly uniform micro- and mesoporous SiO(2) nanoparticles (40-70 nm) are hierarchically functionalized with antagonistic groups: hydrophobic (phenyl) on the internal pores and hydrophilic (methyl-phosphonate) on the external surface. Considering the large hydrophobic internal coating and the long-term colloidal stability, these systems are suitable nanocarriers by using the host-guest appro...

Periodic mesoporous titanium phosphonate (PMTP-2) monoliths were synthesized by combining autoclaving process and evaporation-induced self-assembly strategy, which was functionalized by ClSO(3)H treatment, acting not only as an ion exchanger with large ion exchange capacity but also as a strong acid catalyst possible for some low-temperature reactions.

A novel electrochemical assay to quantify transglutaminase activity is reported. The assay is based on the enzyme-controlled diffusion of Fe(CN)6(3-/4-) through amino-functionalized nanochannels of a mesoporous silica thin film on a Au surface in the presence of N-benzyloxycarbonyl-L-glutaminylglycine.
