The as-synthesized amine-functionalized MCM-41 material was prepared through direct synthesis by co-condensation of tetraethyl orthosilicate (TEOS) with 3-aminopropyl triethoxysilane (APS) at different molar ratios and a pH of approximately 13 for CO

In this study, monoamine 3-aminopropyl silane (APS) grafted on silica supports were prepared either by post-modification of mesoporous template-free SBA-15 and nonporous fumed silica with 3-aminopropyl triethoxysilane (APTES) or by direct synthesis u

The characteristics and CO2 adsorption of mesoporous silicas including MCM-41, SBA-15, and pore-expanded MCM-41 with pore size in a range of 2–17 nm, modified by mono-, di-, and tri-aminosilanes were examined in this study. The adsorption data show

Highly dispersed palladium nanoparticles containing mesoporous silicas MCM-41 and MCM-48 were prepared by one-pot synthesis. The method consists of the simultaneous formation of CTA + surfactant templating MCM-41 mesophase and CTA + micelle-capped Pd

Mesoporous silica films of thickness 0.1–0.2 μm supported on glass and silica wafer substrates were fabricated by sol–gel coating method through P123 and Brij-56 surfactant templating synthesis. Their calcined forms were found to exhibit high po
