Synthesis and characterization of MSU-2 synthesized by using tetraethylorthosilicate and Triton X-100

Adsorption technology is one of the well-established gas separation techniques as it can minimize cost and energy requirement for CO2 separation. Mesoporous silicas such as MSU-2 appears to be a good adsorbent as it comprises of three-dimensional (3D) wormhole framework structures that are highly in...

Adsorption technology is one of the well-established gas separation techniques as it can minimize cost and energy requirement for CO2 separation.

In this study, MSU-2 was prepared by using tetraethylorthosilica (TEOS) as a source of silica in the presence of non- ionic polyethyleneoxide (PEO)-based surfactants under an acidic condition where the pH is 2 at 55 °C for 48 hours via the fluoride-assisted two-step synthesis process.
