Research Abstract |
In order to reduce the CO_2 emissions from global warming issue, the novel solid absorbent based on alkaline earth oxides material was proposed. The effects of addition of other alkaline earth metal oxides to CaO on the CO_2 adsorption energy were also investigated both theoretically and experimentally. On the basis of these results, the favorable process and materials for CO_2 reduction using BaO-TiO_2 or Li_2O-TiO_2 were studied. Moreover, the large scale ab-initio calculations were performed for an accurate estimation of adsorption energy of CO_2 on the CaO and BaO (001)surfaces.
