In this latest work, which is featured as Front Cover in Advanced Materials vol 28 issue 45, our group explored the Au-Pt-Ni core-sandwich shell nanorods for high selectivity H2O2 production via direct oxygen reduction. The epitaxial growth allowed for the tuning of the oxygen reduction pathway to selective 2e- reduction. It is also reported that the transitional high-work-function Pt at the interface is believed to further influence the electrical properties of the Ni shell as well as tuning the degree of lattice strain, and hence further positively affecting the catalytic properties of the core-shell NRs. The findings here were of great implications for tunable two-electron or four electron oxygen reduction by heteroepitaxial growth of multishelled structures.
