| Outline of Final Research Achievements |
The nanoparticle fabrication method by the quantum beam (accelerated electron beam, gamma ray, etc.) irradiation to ionic liquid (IL) can produce a wide variety of nanoparticles including unstable metals in aqueous solution without a reducing agent and a stabilizing agent for the produced nanoparticles. However, because IL is usually more expensive than other solvents, using cost-effective ILs like choline-based ones, we investigated the condition for obtaining the nanoparticles similar to those produced in conventional ILs and finally succeeded in finding it. In addition, the method for producing platinum-nickel alloy nanoparticles, which are expected to be one of next-generation oxygen reduction electrocatalysts, and the approach for supporting such nanoparticles to the carbon black surface were successfully established.
