• resulting material, resulting in a high yield of 81% and an impressive BET surface area of 1365.4 m2·g−1. At 25 °C and 1 bar, M-100Fe@Fe2O3#1.80 showed a CO2 adsorption capacity of 1.10 mmol·g−1 and an IAST-predicted CO2/N2 selectivity of 18, outperforming conventional adsorbents in CO2/N2 separation

• . Importantly, this route opens a new approach to utilizing Fe2O3-based waste materials from the iron and steel industry in manufacturing Fe-based MIL-100 materials. Keywords: CO2/N2 separation; Fe2O3 nanoparticles; hydrothermal reaction; IAST-predicted CO2/N2 selectivity; MIL-100(Fe); Introduction Metal

CO2/N2 separation performance To evaluate the effectiveness of CO2/N2 separation in the as-prepared samples, the adsorption behavior of CO2 and N2 was investigated at pressures ranging from 0 to 100 kPa at 298 K

• nucleation stage. Under the optimized conditions, CO2/N2 separation factor and CO2 gas permeance of the optimized ZIF-8 membrane were 5.49 and 0.47 × 10−7 mol·m−2·s−1·Pa−1, respectively. The as-synthesized ZIF-8 membranes exhibited comparable gas separation performance with the best results of the same type
