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.
纳米多孔金钯(AuPdNPore)合金催化剂在共轭环戊烯酮与硅烷的直接1,4-氢硅烷化反应中,相比于单金属纳米多孔金和钯催化剂,表现出更优越的化学选择性和高催化活性。AuPdNPore催化剂的增强催化性能主要源于其纳米多孔结构和金钯合金的协同效应。
