Abstract
The nanoporous AuPd (AuPdNPore) alloy catalyst showed superior chemoselectivity and high catalytic activity for the direct 1,4-hydrosilylation of the conjugated cyclic enones with hydrosilane in comparison with the monometallic nanoporous Au and Pd catalysts. The enhanced catalytic properties of AuPdNPore arise mainly from the nanoporous structure and the synergistic effect of the AuPd alloy.
摘要
纳米多孔 AuPd（AuPdNPore）合金催化剂在与硅烷的共轭环状烯酮的直接 1,4-硅氢化反应中表现出优异的化学选择性和高催化活性，优于单金属纳米多孔 Au 和 Pd 催化剂。AuPdNPore 的增强催化性能主要源于纳米多孔结构和 AuPd 合金的协同效应。
