Abstract
TiO2 nanoparticles were pretreated with ethelendiamine (EDA) to synthesize amine-functionalized TiO2. The mixed matrix membranes (MMM) comprised of amin-functionalized TiO2 inside polysulfone (PSf) matrix were fabricated and characterized for gas separation. The effects of the amin-functionalized TiO2 loading on the gas permeation properties of the MMM were investigated by varying the amin-functionalized TiO2 loading in the PSf matrix from 0ñ10 wt%. The fabricated amin-functionalized TiO2/PSf MMM were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared spectroscopy (FT/IR) and pure gas permeation test. Gas permeation measurement showed that MMMs embedded with different amount of amin-functionalized TiO2 exhibited different separation performances. For example, in MMMs containing 10 wt% amin-functionalized TiO2, the permeability of N2, CH4, CO2 and O2 increased up to 0.69, 0.8, 3.5 and 1.1 GPU respectively. Due to the higher interaction of amine groups on F-nano TiO2 with polar gases, amin-functionalized TiO2 possessed better performances in terms of permeability and selectivity in comparison to pure TiO2. The results revealed that the functionalization of TiO2 has improved the gas permeability of prepared membranes.
