“…An interesting approach was used by Takahashi et al [17] to obtain organic-inorganic hybrid membranes for fuel cells from 3-glycidoxypropyltrimethoxysilane (GPTMS), N-(3-triethoxysilylpropyl)-4,5-dihydroimidazole (NESPHI) and 1,3-propanesulfone (PS) through a simple one-pot process. The membranes were prepared by the sol-gel method through hydrolysis and condensation reactions of GPTMS, NESPHI and PS at various molar ratios (GPTMS/PS = 1:1, 1:2, NESPHI/GPTMS/PS = 1:1:2, 1:2:3, 1:3:4).…”

Proton conductive organic-inorganic membranes were synthesized based on acrylic monomers and silica inorganic component, derived as a result of sol-gel transformation of precursor-3-methacryloxypropyltrimethoxysilane (MAPTMS). Kinetics of polymerization in situ was investigated by laser interferometry. Membranes characterization includes water and methanol uptake, contact angle and proton conductivity at different temperatures. Activation energy values for proton conductivity in prepared membranes were evaluated. The obtained hybrid membranes demonstrated high proton conductivity making them attractive for the use in fuel cells.

“…They can react with a wide variety of nucleophiles with carbon–oxygen bond cleavage and thus behave as a sulfoalkylating agents. The resulting alkylsulfonates serve as additives in organic baths, monomers, colours and wetting agents . Moreover, they have been extensively applied as effective acid catalysts in organic transformations .…”

n-Butylsulfonated nano-titania (n-TiO 2 -NH-(CH 2 ) 4 -SO 3 H) as a highly efficient and reusable nanocatalyst was prepared by grafting 2,4-toluene diisocyanate as a bi-functional covalent linker onto a nano-titania support, followed by reduction and then ring opening-reaction of the synthesized amine with 1,4-butanesultone. Fourier transform infrared spectroscopy, X-ray diffraction, field-emission scanning electron microscopy and thermogravimetric analysis were used to characterize the catalyst. The catalytic activity of n-TiO 2 -NH-(CH 2 ) 4 -SO 3 H was evaluated in the synthesis of tetrahydrobenzo[b]pyrans, which affords high yields. Statistical experimental design was applied as an efficient and powerful method to achieve the optimal conditions for this catalytic reaction leading to high yield. Moreover, the catalyst was recovered and reused at least six times without a significant decrease in catalytic activity.
