The design of new functional nanomaterials for enhancing oxygen reduction reaction (ORR) is highly desirable for promoting the development of fuel cell and lithium air battery devices. In this seminar, I will focus on my recent advances in rational design and controlled synthesis of high-quality multicomponent nanocrystals for enhancing ORR. I will start with three examples on how to engineer FePt NWs, FePtPd/FePt core/shell NWs and graphene-FePt NPs composite for getting advanced Pt-based catalysts for ORR with extremely high activity and stability. After that, I will move to non-Pt catalysts such as graphene-Co/CoO NPs and M/CuPd NPs (M=Ag, Au), which exhibit comparable and even higher ORR activity and stability than commercial Pt catalyst.
