Outline of Final Research Achievements

In this research, we synthesize a mesoporous calcium carbonate, which undergoes self-assembled nanostructure formation through an aggregation of the colloids. All polymorphs; calcite, aragonite, and vaterite of meso-porous calcium carbonate are individually prepared. We then applied the mesoporous calcium carbonate powder to formaldehyde vapor adsorbent. We measured the adsorbed amount of gaseous formaldehyde and find that the vaterite phase powder has ca. 2 times larger adsorption per unit area than the calcite phase one.
