　　摘要： 

　　Recent advance in nano-fabrication has made it possible to design and synthesize nanoparticles with nearly precise controls on nanoparticle size, shape, composition and structure for catalytic applications. In this talk, I will summarize the common methods we used to synthesize monodisperse nanoparticles, especially intermetallic nanoparticles, core/shell nanoparticles, nanowires and their self-assemblies on graphene (or N-doped graphene) surface. I will use Au-, Pt-, and Cu-based elemental and alloy nanoparticles as examples to demonstrate the rational tuning and enhancement of nanoparticle catalysis for selective electrochemical reduction of proton, oxygen, and carbon dioxide for renewable energy applications.
