摘　　要：The noble metal rhodium(Rh)nanostructures have wide applications in catalysis and electrocatalysis.In this work,a series of Rh Ni alloy nanostructures with different Rh/Ni atomic ratios can be synthesized by one-step wet chemical method.By adjusting Rh^(Ⅲ)/Ni^(iⅡ)feed ratio,high-quality one-dimensional Rh_(1)Ni_(1)alloy nanodendrite assemblies(Rh_(1)Ni_(1)-NDs-As)can be synthesized selectively.Electrochemical measurements show that the introduction of Ni can enhance the electroactivity of Rh nanomaterials for methanol oxidation reaction(MOR)in alkaline media.For potential practical application,Rh_(1)Ni_(1)-NDs-As reveals improved electroactivity and durability for MOR compared to commercial Rh nanoparticle due to the particular morphology,Ni-doping,high electrochemical active area,and excellent anti-poison ability.Considering the facial synthesis and high electroactivity/durability,Rh_(1)Ni_(1)-NDs-As may be promising anode catalysts in direct methanol fuel cells.
