| Outline of Final Research Achievements |
Carbon dioxide, CO2, is the primary greenhouse gas, and its reduction is an urgent issue. We have studied the adsorption and activation of CO2 for the conversion of it to methanol by using copper clusters as catalysts. One of the advantages of the use of the clusters is the ease of designing their geometric and electronic structures in terms of the number of constituent atoms and the composition. In this research project, we have focused our attention to the survey of the promoter for the copper clusters mainly, and improved the probability of the adsorption of CO2 and its activation by the addition of an early transition metal atom like titanium and so on. The promoter atom makes for the interaction between the cluster and CO2, and CO2 can adsorp onto the cluster dissociatively. Additionaly, we have developed an experimental apparatus to elucidate the geometric and the electronic structures of the reaction intermediates by helium nanodroplet isolation spectroscopy.
