摘要：

The　Au@Rh　core-shell　nanoparticles　(NPs)　with　Rh　depositing　on　the　spherical　Au　NPs　were　synthesized　for　the　first　time　using　successive　reduction　method.　Au　NPs　were　prepared　by　reducing　HAuCl4　with　L-ascorbic　acid　as　the　reducing　agent　and　cetyltrimethylammonium　bromide　(CTAB)　as　the　capping　agent.　Au@Rh　NPs　were　then　obtained　by　reducing　RhCl3　in　the　presence　of　the　pre-synthesized　Au　NPs.　The　morphology　of　the　Au@Rh　NPs　is　dendritic.　Au@Rh　NPs　with　molar　ratios　Au:Rh　of　5:1,　2:1,　1:1　and　1:2　show　that　the　Rh　shell　is　polycrystalline　and　the　growth　of　Rh　on　the　Au　NPs　is　heterogeneous　nucleation.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
