The chemical vapour deposition technique was applied to obtain Ti/SBA-15 composites. Titanium(IV) tetraisopropoxide (TTIP) and titanium(IV) tetrabutoxide (TNBT) as sources of TiO2 were deposited on mesoporous silica (SBA-15) from the gaseous phase at 180–200 °C treated 250 in air. X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy used for structural investigations. ...

N-Propylsalicylaldimino-functionalized SBA-15 mesoporous silica was prepared, characterized and used as an adsorbent for heavy metal ions. The organic-inorganic hybrid material was obtained using successive grafting procedures of SBA-15 silica with 3-aminopropyl-triethoxysilane and salicylaldehyde, respectively. For comparison an amorphous silica gel was functionalized using the same procedure....

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.

Pre-synthesized ruthenium dioxide nanoparticulates (RuO(2) NPs) with low level of aggregation were well dispersed in mesoporous silica SBA-15. As a catalyst for water oxidation, the supported RuO(2) NPs exhibit excellent catalytic activity and recyclability. The initial turnover frequency (TOF) is to date the highest among comparable RuO(2) catalysts.
