Formation of titanium nitride nanoparticles within mesoporous silica SBA-15.
We report the first synthesis of titanium nitride (TiN) nanoparticles inside the nanoscale channels of mesoporous silica SBA-15. The TiN precursor, Ti(NMe(2))(4) in toluene, was incorporated into the methyl group-modified channels of the SBA-15 powder. The functionalization of pore surfaces with methyl groups generates hydrophobic surfaces that facilitate impregnation with Ti(NMe(2))(4) and min...
متن کاملModified SBA-15 mesoporous silica for heavy metal ions remediation.
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....
متن کاملMesoporous silica SBA-15 sheet with perpendicular nanochannels.
Free-standing thin sheet form of mesoporous silica materials with perpendicular orientation is a much desired materials for its possible applications in catalysis, mask, and separation. A three component amphiphile system of sodium dodecyl sulfate/hexadecyltrimethylammonium bromide/pluronic-123(C(16)TMAB/SDS/P123) was employed to template the condensation of sodium silicates for the formation o...
متن کاملModification of mesoporous silica SBA-15 with different organic molecules to gain chemical sensors: a review
The recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. The fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...
متن کاملA study on the catalytic activity of a new acidic ordered mesoporous silica (SBA-15)
SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as a catalyst. This mesoporous silica due to silanol groups is easily functionalized by various organic materials. A new acidic ordered functionalized mesoporous silica (SBA-15-Aminopropyl-Benzyl-SO3H) has been introduced as an efficient catalyst for ...
