The PdAu random alloy nanoparticle catalyst shows excellent catalytic activity for heterogeneous molecular formations, whereas monometallic Pd or Au catalysts were ineffective. The Pd/Au ratio in the alloy had a significant impact on its catalytic performance, and the catalyst with a low Pd concentration exhibited excellent activity. The concerted catalysis of Pd and Au adjacent on the alloy surface is responsible for the specific catalytic performance.

钯和金在合金纳米粒子上的协同催化用于高效多相分子转化

PdAu无规合金纳米颗粒催化剂对异质分子形成显示出优异的催化活性，而单金属Pd或Au催化剂无效。合金中的Pd / Au比对其催化性能有显着影响，并且Pd浓度低的催化剂表现出优异的活性。合金表面上相邻的Pd和Au的协同催化作用决定了特定的催化性能。
