| Research Abstract |
The exploitation of synthesis method of shape-controlled nano-particle is important to design for new materials and higher active catalyst. The structural and electrochemical properties of shape-controlled Ag and Pt particle have studied using voltammetry and infrared spectroscopy. The surface structure and electrochemical properties of cubic Ag particles are similar to those of Ag(100). The electrochemical estimation of Pt particles suggests that the planes of the cubic and cuboctahedral Pt nano-particles are composed of step-terrace and atomically flat terraces, respectively. IR results indicate that on-top CO adsorbed on the edges is oxidized at more negative potential than that on the planes. Edge sites of the nano-particles promote CO oxidation.
