Phase transition of mesoporous SiO2 impregnated with an organic templating agent by post-synthetic microwave heatingSpringer Science and Business Media LLC - Tập 15 - Trang 93-99 - 2006
Soo-Hyun Jang, Wha-Seung Ahn
Mesoporous silica SBA-15 samples were subjected to microwave heating for 10–40 min at 393 and 443 K after dry-impregnation with TPAOH (tetrapropylammonium hydroxide) to prepare a mesoporous material with zeolytically ordered pore walls. Physicochemical properties of the materials prepared were characterized by XRD, N2 adsorption at 77 K, SEM, TEM, UV–vis and FT-IR spectroscopies. These investigati...... hiện toàn bộ
Preparation of zeolite-cellulose composites for water disinfectionSpringer Science and Business Media LLC - Tập 28 - Trang 1459-1468 - 2021
Chen Chen, Gongguan Wang, Xiaowen Xu
The drinking water shortage is globe concern currently, thus, developing an economical, green, antibacterial composites is urgent. Here, we report a simple and scalable strategy to synthesize zeolite-cellulose composites by the filter paper immersed in the precursor solution of synthetic zeolite. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray f...... hiện toàn bộ
Novel porous organosilica containing amino and β-cyclodextrin groupsSpringer Science and Business Media LLC - Tập 20 - Trang 663-671 - 2012
Stephanie Degoutin, Maryse Bacquet
The elaboration of new hybrid mesoporous silica materials containing β-cyclodextrin groups and amine functions is reported. The synthesis is based on a direct co-condensation between β-CDAPS, a hybrid precursor obtained by reaction between tosyl-β-cyclodextrin and aminopropyltrimethoxysilane previously described, and tetraethyl orthosilicate via a sol–gel pathway templated by three different surfa...... hiện toàn bộ
Gamma radiation mediated catalytic process for hydrogen generation by water decomposition on NaNO3 surfaceSpringer Science and Business Media LLC - - 2024

The constituent parts of systems where radiation-catalytic processes occur usually differ in terms of mass and electron density, structural characteristics, electro-physical and chemical properties. Therefore, interaction between phases in any form has a sharp effect on the direction and parameters of the processes in individual components. The resulting X-ray diffraction pattern was mainly determ...... hiện toàn bộ
