Pd-doped SiO2 organic-inorganic hybrid material (Pd/M-SiO2) was prepared by sol-gel method and characterized by XRD, FTIR spectra and TG/DTG analysis. The most probable kinetic mechanism function, apparent activation energy and pre-exponential factor of the thermal decomposition for Pd/M-SiO2 material were calculated using the combined Coast-Redfern intergral and Αchar differential methods. Pd element in noncalcined Pd/M-SiO2 materials exists in PdCl2 form. FTIR spectroscopy confirmed the existence of hydrophobic Si−CH3 groups. The thermal decomposition process of Pd/M-SiO2 materials can be divided into four stages, with different mechanism functions. The activation energies are 76.37, 146.85, 208.90 and 413.89 kJ·mol−1 for the four stages, respectively, and the pre-exponential factors are 5.04×1012, 7.14×1013, 2.93×1012 and 6.56×1019 s−1, respectively. There is no obvious influence of the existence of metallic Pd0 on the thermal decomposition of methyl.

In this paper a novel hybrid organic–inorganic amino hybrid material monolithic column for capillary electro chromatography (CEC) is preparation and characterization. The amido hybrid material monolithic column was prepared in situ co-condensation of tetraethoxysilane (TEOS) with 3-aminoproplytriethoxysilane (3-APTES) via sol-gel procedure. The all kinds of factors that effect the morphology of monolith column were investigated. The results showed that the structure of monolithic column could be adjusted easily through altering the composition of sol solution.

This work successfully prepared an UV curable organic-inorganic hybrid material consisting of organic modified colloidal silica. Applications of UV curable organic-inorganic hybrid materials include abrasion resistant coatings, photo-patternable thin films and waveguides. Colloidal silica containing reactive functional groups were also prepared by reacting organic silane and tetraethyl orthosilicate (TEOS) using sol-gel process. In addition, the efficiency of grafting organic moiety onto silica nanoparticles was investigated by applying TGA and FTIR techniques. Experimental results indicated a strong interdependence between surface modification efficiency and solution pH. Acrylate-SiO2 hybrid formation could result in a shifting of thermal degradation temperature of organic component from about 200°C to near 400°C. In addition, the stability of organic modified colloidal silica in UV curable formula and the physical properties of resulting coatings were discussed. Furthermore, the morphology of organic modified colloidal silica was investigated by performing TEM and SEM studies‥
