Outline of Final Research Achievements

Surface structure of the shape controlled Pt particle has been investigated by filed ion microscopy and electrochemical measurements. Cuboctahedral Pt particles with different size are synthesized using new capping regents. The electrochemical measurement was performed using Pt particles loaded on the Au probe. The voltammograms show characteristic behavior of shape controlled Pt particle. The activity for the oxygen reduction reaction is higher than that using rotating disk electrode because uniform shape particles are loaded on Au probe. For the FIM measurement, the improvement of loading method is needed.
