Post-combustion CO 2 capture using mesoporous TiO 2 /graphene oxide nanocomposites

•TiO2/GO nanocomposites with different GO content prepared by colloidal blending.•Synthesized nanocomposites systematically evaluated as adsorbent for CO2 capture.•TiO2/GO have CO2 adsorption capacity of up to 1.88mmolg−1 at 25°C.•TiO2/GO feature fast CO2 uptake kinetics and high CO2/N2 selectivity.•The nanocomposite also exhibit low energy consumption for regeneration.
