In this work, PtRu/CNTs catalysts were prepared by pulse potential plating methods. The particle size and loading level of catalysts were measured by changing the plating time and pulse interval of pulse potential plating method. Electrochemical activities of PtRu/CNTs catalysts were measured by cyclic voltammetry (CV). PtRu/CNTs catalysts showed an increased the electrochemical activity of methanol oxidation up to 24min and a slightly decreased activity over 24min. The electrochemical activity was increased with increasing of the pulse interval. Consequently, it was found that optimal plating time was 24min and optimal pulse interval was 0.5s for electrochemical activity of PtRu/CNTs catalysts.
