“…Depending on the drying conditions the binary oxides could be obtained as aerogels, either by supercritical drying Pajonk et al [14], Dusi et al [15],or by silanization of the material previously to a conventional drying Sotelo et al [16].Additionally, non-hydrolytic sol-gel routes have been also reported in the literatureHay et al [17].…”

Nanosized Titanium dioxide (TiO 2 ) powder was synthesized via sol-gel method using titanium tetraisopropoxide (TTIP) as the precursor. The as prepared nano powder was used for further characterization. The phase transformation was investigated by an X-ray diffractometer (XRD). The anatase structure of titanium dioxide was obtained after calcination. The microstructure was characterized by a Scanning Electron Microscope (SEM).

“…[1][2][3][4][5] Silica is the most highly porous nanostructured material currently available, and has a large surface area, high porosity, and low bulk density. 6 In contrast with silica prepared with expensive alkoxides like tetraethoxysilane (TEOS), 7 our silica can be prepared in mass production for use in the industry by sol-gel polymerization of inexpensive sodium silicate precursor and dried at atmospheric pressure for green chemistry.…”

Multinuclear solid-state nuclear magnetic resonance (NMR) experiments were performed to investigate the local structure changes of nanoporous silica during hydrothermal treatment and surface modification with 3-aminopropyltriethoxysilane (3-APTES). The nanoporous silica was prepared by sol-gel polymerization using inexpensive sodium silicate as a silica precursor. Using 1 H magic angle spinning (MAS) NMR spectra, the hydroxyl groups, which play an important role in surface reactions, were probed. Various silicon sites such as Q 2 , Q 3 , Q 4 , T 2 , and T 3 were identified with 29 Si cross polarization (CP) MAS NMR spectra and quantified with 29Si MAS NMR spectra. The results indicated that about 25% of the silica surface was modified. 1 H and 29 Si NMR data proved that the hydrothermal treatment induced dehydration and dehyroxylation. The 13 C CP MAS and 1 H MAS NMR spectra of 3-APTES attached on the surface of nanoporous silica revealed that the amines of the 3-aminopropyl groups were in the chemical state of NH 3 + rather than NH 2 .
