Abstract The various applications of multi-metal nanocrystals were reported in fuel cell, organic catalysis, SERS and hydrogen storage materials application. Among others, PdPtCu alloy nanocrystal is important due to have different properties. Especially, tri-metal alloy nanoparticles (NPs) reported shape of sphere. However, we demonstrate that PdPtCu alloy dendritic nanoparticles (DNPs) could be exclusively prepared with generally controlled nanoparticles. Facile synthesis of PdPtCu alloy DNPs by using ascorbic acid as a reducing agent and cetyltrimethylammonium chloride (CTAC) as a capping agent is presented. The synthesized PdPtCu alloy DNPs were characterized by transmission electron microscopy (TEM), scannig electron microscopy (SEM), X-ray diffraction (XRD), and cyclic voltammetry (CV). The PdPtCu alloy NPs present efficient electrocatalysis with methanol oxidation (MOR) and ethanol oxidation (EOR).
