Abstract

Three kinds of plasmonic mesoporous AuAg (mesoAuAg) nanospheres, including well-alloyed mesoAuAg, hollow mesoAuAg, and core–shell Ag-mesoAu nanospheres, were successfully synthesized by carefully controlling the reduction kinetics of metal precursors in the presence of a functional surfactant, C₂₂H₄₅N⁺(CH₃)₂–C₃H₆–SH(Cl⁻). The resulting mesoAuAg exhibited a remarkable structure-dependent electrocatalytic performance toward methanol oxidation reaction.
