Abstract

We report the effect of graphene oxide (GO) on a facilitated CO₂ transport membrane consisting of copper nanoparticles (CuNP) prepared in situ in ionic liquids (IL), such as 1-hexyl-3-methylimidazolium nitrate (HmimNO₃) and 1-methyl-3-octylimidazolium tetrafluoroborate (MoimBF₄). The highly smooth surface of the GO was characterized by atomic force microscopy, and the interactions between the GO and the IL were investigated by Fourier transform-Raman spectroscopy. With GO, the fabricated HmimNO₃/CuNP/GO and MoimBF₄/CuNP/GO composite membranes showed CO₂/N₂ separations of 8.7 and 30.7, respectively, with enhanced CO₂ gas permeance compared to IL/CuNP composite membrane without GO. This implies that graphene oxide can be used as an effective additive in nanocomposite membranes for enhanced CO₂ permeance.
