Multi-core MgO NPs@C core–shell nanospheres for selective CO2 capture under mild conditions

Author affiliations

Abstract

The core–shell structures have attracted attention in catalysis, because the outer shells isolate the catalytically active NP cores and prevent the possibility of sintering of core particles during catalytic reaction under physically and chemically harsh conditions. We aimed to adopt this core–shell system for CO2 sorption materials. In this study, a composite material of multi-core 3 nm-sized magnesium oxide nanoparticles embedded in porous carbon nanospheres (MgO NPs@C) was synthesized by a gas phase reaction via a solvent-free process. It showed selective CO2 adsorption capacity over N2 under mild regeneration conditions.
