“Tuning
Nanocatalysts for Efficient Electrochemical Reactions”
FRIDAY
Abstract
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 Cubased 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.
