| Outline of Final Research Achievements |
The 12CaO・7Al2O3 electride (C12A7:e-) with high surface area was successfully synthesized by the reduction of hydrothermally produced C12A7. The cobalt nanoparticles on C12A7:e- exhibited outsatanding catalytic activity for ammonia synthesis at low reaction temperatures (493-673 K) as compared with a conventional cobalt catalyst. C12A7 catalysts with various anions, such as F- and Cl-, were also synthesized by solid-phase method or hydrothermal method and their structural and catalytic properties were investigated. Among the obtained C12A7 with various anions, the C12A7:F- exhibits the highest catalytic activity for Knoevenagel condensation. Furthermore, the catalytic activity of C12A7:F- prepared by hydrothermal method is much higher than that of C12A7:F－ prepared by solid phase method.
