Sažetak

In this study, the microporous silica membrane was prepared by the template assisted sol-gel method. The surface of the templated silica membranes was modified via two procedures; selective layer, and layer by layer surface modification. The obtained results confirmed that the surface modification procedure is very crucial to the final performance of the membrane. Thus, for the templated silica membrane modified by the first procedure, CO2/N2 permselectivity was achieved at 3.0 and CO2 permeance was 6.3×10–9 mol m–2 s–1 Pa–1, while for the templated silica membrane modified by the second procedure, the CO2/N2 permselectivity was achieved at 11.3 and CO2 permeance was 4.0×10–8 mol m–2 s–1 Pa–1, at room temperature.
