摘　　要：Ag@Ag-Pdx core-shell nanocomposites with various Ag/Pd ratio were deposited on Ag nanoplates using a seed growth method.When physically loaded on C3N4,Ag@Ag-Pd0.077/C3N4 with optimized Ag/Pd ratio could accomplish high catalytic performance for the semi-hydrogenation of phenylacetylene as well as other aliphatic(both terminal and internal alkynes)alkynes and phenylcycloalkynes containing functional groups(such as ester,hydroxyl,ethyl groups)under room temperature and 1 atm H_(2).The alloying and ensemble effects are used to interpret such catalytic performance.
