This document summarizes research into using metal oxide nanoparticles for carbon dioxide capture. The researchers synthesized magnesium oxide nanoparticles by calcining magnesium organic frameworks to form porous oxide networks with high surface areas and pore volumes for CO2 capture. Preliminary results showed the magnesium oxide nanoparticles had relatively high CO2 capture capacity compared to other metal oxides, maintained capacity over 10 cycles of regeneration with less than 1% change each cycle, and may increase regeneration resistance. Further studies are needed to better understand how these materials retain capture capacity after recycling and to test other metals and synthesis methods.
