ETS-10 was ion exchanged by various alkali cations (Li+, Na+, K+, Rb+ and Cs+) and the BET surface area and pore volume was exactly consistent with cationic size; that is, in the order of Li+ > Na+ > K+ > Rb+ > Cs+. It was observed that a single point adsorption capacity was inversely proportional to cationic size. The largest CO2 capacity was observed for Li+-ETS-10 and it is attributed...
One of ETS-10 (Engelhard titanosilicate materials number 10) variants, ETGS-10 was successfully synthesized within limited Ga/Ti molar ratio of 0.1–0.3 using sodium silicate and titanium oxysulfate (TiOSO4) as silica and titanium sources. Like ETS-10 and ETAS-10, the (Na + K)/Na molar ratio has significant effect on the crystallinity and especially purity of final product. The 23 factorial methods...
