Ag@Ag-Pd_x 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-Pd_0.077/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 H₂. The alloying and ensemble effects are used to interpret such catalytic performance.

种子介导的合金 Ag-Pd 壳在温和条件下向炔半氢化反应生长†

使用种子生长方法将具有不同 Ag/Pd 比率的Ag@Ag-Pd _x核壳纳米复合材料沉积在 Ag 纳米板上。当物理负载在 C ₃ N _{4 上时}，具有优化的 Ag/Pd 比的Ag@Ag-Pd _0.077 /C ₃ N ₄可以实现对苯乙炔以及其他脂肪族（末端和内部炔烃）的半加氢的高催化性能在室温和 1 个大气压的 H ₂下含有官能团（如酯、羟基、乙基）的炔烃和苯基环炔烃。合金化和整体效应用于解释这种催化性能。
