报告摘要：In this talk, I willsummarize the recent research on the crystal phase-controlled synthesis ofnovel noble metal nanomaterials in my group. It includes the first-timesynthesis of hexagonal-close packed (hcp) Au nanosheets (AuSSs) on grapheneoxide, surface-induced phase transformation of AuSSs from hcp to face-centeredcubic (fcc) structures, alternating hcp/fcc Au square-like plates from AuSSs,ultrathin Au nanowires containing hcp phase, synthesis of ultrathin fcc Au@Ptand Au@Pd rhombic nanoplates through the epitaxial growth of Pt and Pd on thehcp AuSSs, respectively, the first-time synthesis of 4H hexagonal phase Aunanoribbons (NRBs) and their phase transformation to fcc Au RNBs, the epitaxialgrowth of Ag, Pt, Pd, PtAg, PdAg, PtPdAg, Rh, Ir, Ru, Os and Cu on 4H Au NRBsto form the 4H/fcc Au@metal core–shell NRBs, and the synthesis of4H/fcc-Au@metal sulfide core-shell NRB heterostructures. Currently, my groupfocuses on the crystal phase-based properties and applications in catalysis,surface enhanced Raman scattering, waveguide, photothermal therapy, chemicaland biosensing, etc., which we believe are unique and critically important notonly fundamentally, but also practically. Importantly, the concepts of crystalphase noble metal heterostructures is proposed.
