Outline of Final Research Achievements

We investigated reduction of CO2 into chemical fuels such as methane using catalyst, light irradiaiton, and hydrogen. The results indicate that synergisitc effects between photothermal and plasmomic efects occurred and the reduction activity was improved further. The enhancement effect was influenced by the distance between metal and alloy, light absorption property of the catalyasts and support. The enhancement mechanism was also discussed in this research.

Academic Significance and Societal Importance of the Research Achievements

二酸化炭素還元反応では比較的合成しづらいメタノールを常圧で銅触媒を用いることで初めて産出させることに成功した。メタノールはメタンよりも液体で保持しやすいので、運搬、移動という点でメリットがあると思われる。これらの成功には表面プラズモン共鳴が寄与しており、その効果を様々な触媒、（二酸化炭素還元メタン合成などの）反応系において確認できた。メタンの生成活性を向上させることにも成功した。
