摘要： Trimetallic palladium-copper-cobalt nanoparticles supported on reduced graphene oxide (PdCuCo/RGO) with different molar ratios of Pd, Cu and Co can be synthesized by facile chemical reduction with NaBH4 as reductant and cetrimonium bromide as stabilizer. The morphology, structure and composition of the as-synthesized catalysts are characterized by transmission electron microscopy, X-ray diffraction and Xray photoelectron spectroscopy. The cyclic voltammetry and chronoamperometry are utilized to investigate the electrochemical activities and stabilities of the as-obtained catalysts. The results demonstrate that the PdCuCo/RGO catalyst shows superior catalytic activity and stability for methanol electrooxidation in alkaline media compared with PdCu/RGO, PdCo/RGO, and Pd/RGO catalysts. These findings suggest that the PdCuCo/RGO catalyst possesses a great potential as a promising anode catalyst for direct methanol fuel cells.
