| Outline of Final Research Achievements |
In the present study, we have investigated the preparation of alloy nanoparticle catalysts by using solvated electron with high reducing power. Sodium naphthalenide can be prepared by reacting sodium metal with naphthalene in THF solution. And it is known to be a strong reducing agent (E0 = 3.1 V). We have successfully prepared Co-Mo alloy nanoparticles with a particle size of 4 nm yb using this reducing agent. The Co-Mo alloy nanoparticles loaded on CeO2 exhibits much higher catalytic activity for ammonia synthesis than monometallic catalysts such as Co/CeO2 and Mo/CeO2. In addition, the catalytic activity Co-Mo/CeO2 is comparable to that of Co3Mo3N, even if the amount of loading metal in Co-Mo/CeO2 was only 1/20 of that in Co3Mo3N.
