| The electrochemical performance of fuel cells is affected greatly by the catalyst particle properties, so the deep study of the catalyst particle properties is meaningful and necessary. Recently, the research work is mainly focused on the bimetallic system and a significant number of papers are published on the subject of core-shell structure catalyst. Methods for synthesis core-shell structure of Ag@Pt, Co@Pt, Ni@Pt, Fe@Pt, Pt@Co have been described. The properties of such small particles depend on their composition, size, shape, and method of preparation. Therefore the structure of core-shell thoroughly explains new properties of bimetallic systems, often distinct from those of the corresponding mono-metallic particles.Besides monometallic or alloy structured particles. Core-shell systems are of great interest and have revealed a large range of catalyst properties. Results have been reported for metallic and alloyed core articles covered with a noble metal (usually Pt). Co/Pt,Ni/Pt, Fe/Pt alloys show high activity in comparison to pure Pt catalyst.Our strategy is to reduce [Pt3(CO)6]32- to deposit Pt on Ru core particle. In previous article,J.X.Wang reduce [PtCl6]2- on the surface of Ru nonopaticle directly to synthesis the core-shell structure. K.Vinodgopal added the solution of [PtCl4]2- to RuCl3 and sonicated the mixture by an ultrasound transducer to get the core-shell structure nanoparticles . In this paper we describe a new method for synthesizing core-shell particle system. we present here the alcohol-themal synthesis of core-shell structure Ru@Pt nonopatical by reducing Platnium carbonyl dianions on the surface of Ru particle. The CO-stripping potential shifts to a lower value using this catalyst in comparison to the commercial catalyst Pt/C ( 20 wt. % E-TEK).
