MgO-Al2O3@C spheres were synthesized via a simple sacrificial templating method using resorcinol and formaldehyde. The SEM studies revealed the presence of interconnected nanosized particles within the nanoscale region. The improved CO2 sorption performance is due to the unique Mg-Al-C network which provides a favorable surface structure for the generation of unsaturated O2-. Among the samples tested, MgAl@C-1:2 shows the highest MgO carbonation conversion corresponding to 60% at 40oC with improved cyclic stability for 10 cycles.
